Graphite Electrodes Production and Optimization Practices

Graphite Electrodes Production and Optimization Practices Graphite electrodes are used in both DC and AC electric arc furnaces. Companies who use electric arc furnaces have to cover the cost of these consumable electrodes during production, so optimizing the usage of graphite electrodes is a money-saving opportunity. This paper aims to discuss the production process of graphite electrodes as well as industry practices that are used to enhance the life of electrodes. To produce a graphite electrode, carbon is required. The carbon source for graphite electrodes comes from the petroleum industry as a by-product from the oil refining process. In the refining of crude oil, hydrocarbon chains are cracked in coking units and the resulting fuels are then separated as kerosene, gasoline, and diesel. As chains of hydrocarbons are being cracked in this process, pure carbon becomes deposited on the sidewalls of the coking units. The carbon on the sidewalls accumulates up to a certain point when it is the ground out of the unit. This carbon is called petroleum coke, or petcoke. This is the carbon source for graphite electrodes. After the petcoke is obtained from the oil refinery, it is blended with pitch to make a plastic-like material. (Making a UCAR ® Graphite Electrode) This blend of petcoke and pitch is then extruded through a circular die and cut off in sections. It is then baked at a temperature of above 800 degrees Celsius for a period of one to two weeks. After baking, the electrode is impregnated with more pitch to increase the density of the electrode which lowers electrical resistance and makes it stronger. The electrode is then re-baked at a slightly lower temperature to drive off volatiles found in the pitch. Finally, the electrode is heated to a temperature of about 3000 degrees Celsius to recrystallize the carbon into graphite. This final heating is called graphitization. Graphitization is very important in electrode manufacturing because it provides better mechanical strength and also improves electrical conductivity. The final step in electrode production is machining. The electrodes are machined to specific tolerances. This is especially important at the ends of the electrodes where the joints connect. (D. Klein) A good connection between joints is necessary for mechanical and electrical properties of the electrode. Electrode consumption takes on two forms: Continuous consumption and discontinuous consumption. (Richard J. Fruehan) Continuous consumption contributes 90% of total electrode consumption while discontinuous consumption only accounts for 10%. Even though discontinuous consumption accounts for far less than continuous consumption, discontinuous consumption can also account for furnace downtime which can cost a lot of money. So even though it is a small percentage, it is worthwhile to try to prevent it for the sake of productivity. In continuous consumption, the tip and sidewalls oxidize and the mass of the electrode is reduced. Tip consumption is a function of current and angle. Higher currents and steeper tip angles both yield faster oxidation rates of electrodes. (A. Lefort) Higher currents increase the temperature of the electrode which favors a faster oxidation rate. The steeper the tip angle, the closer the electrode needs to be to the steel bath to arc. Steel is more likely to splash onto the electrode if it is closer to the bath. One way to reduce the oxidation rate of electrodes is to cool them. Water cooled electrodes have been shown to reduce the oxidation rate of the sidewalls by 40% and the tip by 50%. One issue with water cooled electrodes is the flow rate of the water. If the flow rate is too high, water will pour into the furnace and increase the heat loss. The loss of heat can end up costing more than the money saved from reducing electrode consumption, so this is an important factor to conside r in this process. In discontinuous consumption, one of the most obvious techniques to prevent electrode breakage is simply to not ram the electrodes into the steel scrap. Graphite is a soft, brittle material and steel scrap is pretty hard and durable. If these two materials come head-to-head, the steel wins. Another method of discontinuous consumption is tip spalling. (A. Lefrank) This is more prevalent in DC furnaces than in AC furnaces because the DC electrodes see higher temperatures and therefore higher thermal stresses. The temperature gradient can be significant in the tip of a DC electrode and the thermal expansion of graphite can cause enough stress on the tip to break off small pieces. (J. E. Surma) Normally, the arc in a DC furnace will move about randomly, but occasionally the arc will sit in one spot, heating up that portion of the electrode tip creating thermal stresses that cause the tip to spall. Arc deflection control is a practice that has been implemented so when the arc becomes fixa ted on one spot, it will essentially â€Å"push† the arc out from that spot to get it to move about in a random fashion once more. Another practice to prevent the discontinuous consumption of electrodes is to ensure proper torque is applied when installing new electrode segments. The vibrations from the furnace and electromagnetic forces due to the flow of electricity give electrodes a good shaking. This can jostle the segments loose from their joints. This is mainly a problem in DC furnaces because AC furnaces are designed to ensure that the electromagnetic forces work to their advantage. In AC furnaces, the phase sequence is counterclockwise, so the forces on the electrodes due to the electromagnetism of the system only ever tightens the electrode joints. Below is a chart of recommended torque according to electrode diameter from SGL Carbons website and an AC furnace schematic of forces due to phase sequence. One final practice that helps prevent the failure of electrode joints is to turn off the water spray for a few minutes after the addition of another electrode segment. (Richard J. Fruehan) The temperature gradient is much steeper when the water spray operation is active. This thermal gradient can cause a problem when it reaches the joint because of the thermal expansion of graphite. Even if the electrode was tightened with the proper amount of torque, the effects of temperature on the electrode joint is enough to loosen it. This coupled with the furnace vibrations could be enough to cause the electrode joint to fail. In conclusion, graphite electrodes are an essential part of electric arc furnace steelmaking. Since they are consumable, any way to improve the life and efficiency of an electrode saves money in the steelmaking industry. Practices such as water cooling electrodes and optimizing current and tip angle are effective ways of reducing the oxidation of electrodes while taking care not to impact the scrap during melting, ensuring proper torque during installation, and turning off the water spray while adding another segment all help reduce breakage and joint failure.

The Idea of a University :: College Culture Cultural Essays

The Idea of a University People have long assumed that university is the home of the educated and open minded people. People expand their personal horizons here. The public believes university students can deal with the cultural differences of human beings. The public believes students can deal with these differences because university students are exposed to a wide range of academic subjects including Humanities. Humanities exposes students to world literature, art, and geography. The public expects these subjects to aid university students in understanding cultural differences.Use of cultural differences should be emphasized in the universities. These differences should be emphasized not to humiliate or disgrace people but to influence students to accept and acknowledge cultural differences. The world is a complex mixture of people with diverse languages, skin tones, and cultural differences. These differences are the most evident in human beings. People are classified according to one or more of these differences. But the division gives the impression of being a negative one. Exposing these differences in universities and colleges should not be the source any problems. In fact, exposing these differences should help people understand and at times lend a hand to disadvantaged college students. Disadvantaged college students are the majority in college today, were yesterday, and will be tomorrow. At times disadvantaged college students feel ashamed of their cultural background. Disadvantaged college students feel ashamed because they feel other people will put them down. They don t want to talk about it. Concerning shame because of social conditions, Bell Hooks says that Class differences were boundaries no one wanted to face or talk about (95). Yet concealing cultural background can cause misunderstanding among peers. Learning about the class neighbor s cultural background, may perhaps help understand that neighbor s personality. Commenting on cultural background, Mike Rose depicts the life of a Guatemalan boy having trouble in school. The Guatemalan boy is troubled by his past. His brother was killed and dismembered near his house. These incidents are unusual for some people. The place that rose describes is filthy, chaotic, and unkept. this kind of place is the home of many college and university studentsw. Certain college students have had a depressing type of life.

Euthanasia Legalization

Euthanasia Legalization By: Renee Rosenkilde Rosenkilde 1 Although the United States, and the rest of the world, have made astounding inventions and breakthroughs in technology, health care is still subject to criticism. Even in the twenty-first century, there are numerous terminal, chronic, and life threating diseases circling the world. Because of these circumstances, when a patient is diagnosed with a painful disease that will kill them in a short amount of time, they should be allowed to decide how they want to end their life: waiting for the disease to kill them, or instantly receiving assisted suicide and ending their pain immediately.Through the process of active euthanasia, a person diagnosed with a terminal illness can immediately die. Active euthanasia would allow a person with a terminal illness to be administered a lethal medication which will instantly kill them and release them from their suffering. Another form of assisted suicide, passive euthanasia, is eliminating an y medical assistance in keeping a patient alive, until their death.Active euthanasia should be legalized because it is legal according to the constitution, it is a less expensive alternative, certain religions partake in the act of active euthanasia, and overall it will allow a terminally ill and suffering patient to end their misery. Active euthanasia should be legalized throughout the United States because it is legal according to the Constitution. Currently, assisted suicide is only legal in the states of Washington, Oregon, and Montana (ND NA wrtl. org).Active euthanasia would allow a citizen of the United States a painless death, and an allotted time to say goodbye to their friends and family members. Once consent is given from either the patient themselves, or the family, active Rosenkilde 2 euthanasia should be a possibility for someone with a terminal chronic illness. Steven Ertlet comments, â€Å"The bereaved family and friends of cancer patients who died by euthanasia cop ed better with respect to grief symptoms and post-traumatic stress reactions than the bereaved of comparable cancer patients who died a natural death. (ND Ertlet paragraph 1). Whereas passive euthanasia would contribute to an extensive amount of pain and suffering, active euthanasia would allow for an immediate, accessible, and painless death. The Constitution of the United States says, â€Å"†¦certain unalienable rights, that among these are life, liberty and the pursuit of happiness. †¦whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it. † The United States Constitution grants its citizens the right to pursue happiness, which in some cases may be through active euthanasia.The Constitution restates this idea in a more precise form in the Due Process Clause [first section of the fourteenth amendment]: â€Å"No state shall make or enforce any law which shall abridge the privileges or immunities o f citizens of the United States; nor shall any state deprive any person of†¦liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. † The Constitution states that if it is a person’s desire to die through active euthanasia, it shall be provided to them through to the Due Process Law [first section of the fourteenth amendment].In the case that active euthanasia would be the best option for a United States citizen struggling with a terminal illness, active euthanasia should be considered. Euthanasia should be legalized in the United States, because it would allow for a citizen with a terminal illness a quick and painless death as well as abide to the Unites States Constitution. Rosenkilde 3 With the declining economy in the United States, saving money and cutting unnecessary spending is of great importance.With health spending accounting for over 17% GDP [how much a place produces in some amou nt of time] in the United States, it is the highest in the world (NA ND data. wordlbank. org). Cutting this percentage as much as possible would drastically improve the Untied State’s economy. The money spent in hospitals is used to cure patients with different illnesses. Although this is thoughtful on America’s part, in many cases it is unnecessary. If a patient is diagnosed with an incurable terminal illness, there is not much point in wasting money to keep them suffering for as long as possible.Mpoziemski, an online debater at euthanasia. procon. org comments, â€Å"Is it not more compassionate to end a human's suffering then to make them hold on only to die later after a long, drawn out pain filled battle? † (Mpoziemski 2012 paragraph 1). Keeping a patient suffering until they die of natural causes is irrational when it is possible through active euthanasia to end their suffering as soon as possible. As an added note, this would also help save money througho ut this country in drastic numbers. Once approval is given for active euthanasia to be administered, it is can easily save the patient and the hospital money.Certain cancer treatments can be as costly as $10,000, which is added to the accumulating bill for doctor visits, lab tests, room charges, imaging tests, radiation treatments, drugs and other medicines, nurse care, surgery, and homecare (NA ND cancer. org/treatment). Prolonging the life of a patient with an illness is costly for both the hospital and the patient. Instead of paying money to suffer for a longer amount of time, a person with a terminal illness can receive active euthanasia and avoid both the physical and financial pain.Rosenkilde 4 The United States was originally a British colony which British citizens fled to for religious freedom. America seemed as a place where everybody could freely practice their religion. Therefore, when the United States liberated themself from Great Britain, the basis of this country was based off of the freedom of religion. The first amendment of the United States Constitution says â€Å"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof†¦Ã¢â‚¬  (www. archieves. ov amendment 1). According toreligions. pewform. org, Judaism, a religion that over 2% of all American adults practice, accepts the idea of suicide in certain circumstances. A story in the Torah tells of a young man who was told by God to commit suicide in order to end his suffering. The story tells of a young man who was being burned alive by the Romans, and god tells him to end his suffering by breathing in large amount of smoke and flames to kill him more quickly. Also, Jewish people do not associate suicide as murder.Although the Torah explains breaking one of the Ten Commandments â€Å"thou shalt not kill† as a sin, suicide does not abide by this commandment, and therefore is not considered a sin. Another main religion in the Unite d States is Hinduism. Practiced mainly by Americans of Indian decent, this religion has ancient suicidal practices. One example of this is called â€Å"suttee†. This is a ritual practice throughout India in which a wife will commit suicide after her husband’s death so that he would have a partner in the afterlife. †¦[suttee] the Indian custom of a widow burning herself, either on the funeral pyre of her dead husband or in some other fashion, soon after his death. † (http://www. britannica. com/EBchecked/topic/575795/suttee). Another example of Hindu suicide is the practice of prayopavesa. Prayopavesa is when a Hindu will fast (not eat food) until their death. This practice is used under certain circumstances only for the religiously advanced. Rosenkilde 5 Prayopavesa is only used when a person has an incurable terminal illness. Not consuming any food or water will eventually kill the person, most likely faster than the illness would have.The Hindu religion b elieves in the concept of karma: good or bad luck generated by your actions. Some Hindus believe that â€Å"†¦a person who helps other end a painful life and thereby reduce suffering is doing a good deed and will gain good karma. † (http://www. religionfacts. com/euthanasia/hinduism. htm). In all, the United States was based off of freedom of religion, and this concept has been encoded in the first amendment of the constitution. Therefore, if a religion accepts and enforces the practice of assisted suicide (active euthanasia), then it should be legalized throughout the United States.Although active euthanasia is a politically and religiously controversial topic, research can conclude that euthanasia should be legalized across the United States. Due to the fact that the United States Constitution accepts the use of euthanasia, it cannot be ruled as illegal. As well, the United States Constitution, and the entire country, was based off of the freedom of religion. Therefore , if certain major religions accept, and encourage the use of active euthanasia, than the medical procedure should be legalized across the nation so that these religious practices may take place in a safe medical environment.As well, active euthanasia should be legalized because it can save a great deal of money across the United States. With over 17% of GDP used on hospitals and the medical world, taking a person out of their misery would be more effective and less costly. The costs for doctor visits, lab tests, room charges, imaging tests, radiation treatments, drugs and other medicines, nurse care, surgery, and homecare accumulate to increasingly high bills for both the patient and the hospital. Finally, and most importantly, the practice of active euthanasia can quickly, easily, and effectively take a patient with a terminal Rosenkilde 6 llness out of their pain and misery with an allotted time to say goodbye to their loved ones. With a patient dying due to a disease anyways, wo uldn’t it make more sense to end their life quickly and easily instead of keeping them alive to endure a life of pain? Active euthanasia should be legalized throughout the United States, and should be made an option for anyone with a miserable, chronic, long-term, terminal illness.

How to Write a Speech

How to Write a Speech How to Write a Speech When it comes to public speaking – in the student’s case, giving a speech to a classroom of their peers and their instructor – one’s success lies in preparation. Which means that delivering a good speech ultimately depends on the writing a  speech. After all, a speech is like a spoken essay. Some people are natural-born public speakers who can entertain an entire room without a second of planning; however, the student in higher education who is to give a speech (who is also most likely a novice public speaker) should follow these 10 speech writing steps. 10 Speech Writing Steps 1. Plan the speech according to the occasion. The student required to give a speech will probably be speaking in an academic setting, where a serious, informative or persuasive tone will serve them best. Most times, the student will be given a time limit, which should be strictly followed. 2. Recognize the theme/message or purpose of the speech. This will help the student identify which direction they are going to take in the writing/planning/researching of the speech, helping them develop a sort of formula to achieve that purpose. 3. Be creative with the speech’s introduction. Once the student knows what they are going to say, they should consider a brief, interesting way to get their audience’s attention – whether with a joke, an interesting anecdote, famous quote, even a thought-provoking question. 4. Learn how to write a speech outline. This helps the student visualize all the points they need to cover in their speech. 5. Expand on the points in the speech outline. If they’re given a speech in a persuasive manner, they will need a solid thesis statement defended by strong evidence to support their argument. If giving an informative speech for an assignment, the student should incorporate solid, research-based information. In either case, the student must center their speech on the theme, issue, or subject they are discussing, arguing, or analyzing. 6. Incorporate transitional phrases to cover various points. Words like â€Å"First of all,† â€Å"Secondly,† â€Å"Next,† and â€Å"Lastly† help the speaker better transition from point to point, for their own sake and the audience. 7. Don’t forget about the conclusion. Just like with an essay or written assignment, a proper conclusion allows the speaker to tie in all the points of their speech, leaving the audience with a comprehensive understanding of what they just discussed. 8. Write the speech out in full, in essay form. Include the introduction, the points to be covered, as well as transitional phrases, and a conclusion – and then evaluate its effectiveness. Edit if needed. Writing more than one draft helps the student add or remove pertinent information. 9. Ask a friend to revise the written speech; revise the draft based on their feedback. Once the student feels their written speech is nearly completed, seeking the help of another person is beneficial. They will see things the writer may not notice, which will ultimately improve the speech. 10. Read the speech aloud. Before the student rehearses their speech first for familiarization, then memorization, they should read the speech aloud to compare how it sounds with how it reads; this could be the difference in an awkward, boring speech or one that is interesting and gets a higher grade.

Geological History Of Pa Essays - Geology Of New Jersey, Free Essays

Geological History Of Pa Essays - Geology Of New Jersey, Free Essays Geological History Of Pa The earth is an ever-changing chunk of rock to put it at the lowest level of comprehension available. This rock that we call home is brewing with billions of life forms and is constantly changing every day. This can be attributed to the various cycles that are at work on this planet of our, from the hydrological system to the rock cycle the earth is an ever changing form. Pennsylvania is just a small part of this system we call our home. Formed millions of year ago by tectonic collisions and molten rock Pennsylvania is a part of the earth full of specially minerals and geological features that stand out as being come of the best in the world. What would our state be with out its coalmines and steel mills. Which of course are only possible through the unique geographic features of our state. The Pre-Achaean, Achaean and Proterozoic Eras. Geologists believe that Pennsylvania was formed by parts of the Laurentian continental crust block. This crust block is made up of many micro plates, which were accreted during the period from about 2.5 billion to 1.0 billion years ago. This was previously part of an even larger crustal block called Rodinia. Geologist believes that PA is full of rocks that were once part of this crustal block. These rocks are known as the Greenville rocks. Greenville rocks are metamorphic rocks composed mainly of gneiss. Some of these rocks are visible in Southeastern PA but most are buried deep within the surface of PA. The Cambrian and Ordovician Periods This is really the period that life started to develop in the state of Pennsylvania. Now how did life star in this state you may ask, well here is how. At the start of the Cambrian period water from the Ocean spread inland across North America. Pennsylvania got in the way of this and was covered with a shallow layer of water which created unique environments for both life as well as the opportunity of new deposition of sediment. This water cover also had a big part in eroding away water channels as well as leaving large deposits of sediment. During the late Ordovician era materials from the arc and the floor of the Ocean were thrust onto the North American plate. This phenomena was called Taconic orgogeny, this played an important part in the development of mountains in PA. This Taconic orogeny created the mountains that lay to the northeast of PA. The Taconic orogeny, which deposited many harmful types of sediment, also saw the end to many life forms due to this heavy disposition of harmful materials. The Silurian Period During this period the mountains that were formed by the Taconic orogeny were still a good source of sediments. PA was covered with clastic sediment form these mountains for the first half of this 25 million year period. Sand and gravel composed mainly of quartz were deposited by stream to the eastern parts of the state. There was also quartz sand carried further west and deposited on the beaches and shores. Even today some of this sediment can still be found along the linear ridges of the Appalachian Mountain section of the Ridge and Valley province. In the western part of the state more mud was deposited then anything and even further west was the disposition of carbonate. This was also the time when many rocks were being chemical weathered and creating large amounts of iron, which were later, mined throughout most of the 1800s. The mountains that were created by the Taconic Orogreny were eroded during this time and stopped becoming a source of clastic sediment. In the northwestern part of PA during this time a supersaturated basin had formed with limited circulation. Once this basin evaporated the area was left full of gypsum and halite. This was also a crucial period for life. It saw the first fish appear on the earth. The Devonian Period This period was a relatively slow time for PA until the end of it. This period saw more deposition of carbonate for a few million more years. It also saw the formation of the Acadian Mountains. These were formed just east of PA when there was a collision

How Classical Music Infulence Human Lives Research Paper

How Classical Music Infulence Human Lives - Research Paper Example Most homes had at least a musical instrument that was played with lesser or greater skill. Concerts were big events and the people who liked attending them were mostly the rich ones. The pieces prepared for the concerts were longer since people were merely dying to listen to the music. The people could not miss the concerts and wait to pick the cds from music stores the following day. A story is told of J.S. Bach who walked several miles to listen to a performance by a great organist called Buxtehude. Symphonies structured into works of many movements exposed listeners to a variety of intellectual experiences and moods. Music involving dance invited listeners to enjoy. Concerts were great events and these works were not performed all at the same time as they are these days. Originally, symphony movements were separated by other kinds of performances or pieces of music altogether. Today, the cultural, social and aesthetic realities are very different. The time constraints, needs and m usic availability are all different. One can easily turn of or change what they are listening to literally at any time of the day or night. There is need for a totally different approach. The music of today is neither worse nor better, but rather fits this place and time in history. Fortunately, there is always great classical works to return to for inspiration and pleasure. What's the Connection between Classical Music and People's Lives? Classical music has attracted varying perspectives worldwide. During the times of Bach and Mozart, classical music flourished, but today some people, especially the young, perceived it as boring and old fashioned. However, they are missing out since this music is beneficial for the human body and brain. Classical music makes humans... This essay approves that classical music continually developed and evolved from the time of Mozart and Beethoven. It is not about to stagnate anytime soon, but it is continually pushing the sound and music boundaries. Other genres are on constant influence by the advancements in classical music. For instance, Stockhausen's music greatly influenced the Beatles. Many contemporary composers of jazz have employed freedoms and techniques that originated from classical music. Modern classical music has had influence on pop, rock and other genres of music. Rather than blocking the creative ability of contemporary musicians, classical music fertilises and enriches it. The music provides the tools necessary in innovation of other kinds of music. Out of this kind of music come many innovations like the twelve tone method and the ubiquitous staff notation system. This report makes a conclusion that regardless of whether or not one is classical music fan, he/she can always find something that inspires. It could be a specific piece of music, the music of specific composer, the passion and power of musicians performing collectively in perfect harmony or the heartbreaking drama of a particular opera. One can find his/her connection to this kind of music by listening with an open mind. A listener can also perform classical music. Several schools have orchestras and bands. Some cities have municipal bands or youth orchestras. Classical music is the backbone of music, although nowadays people do not appear to really appreciate or enjoy it as they should. People lose out on the benefits the music has on the human body. They need to embrace change and attempt new things, and they could realize that they love classical music. Classical music is among the oldest and most-loved music genres of all times, which can make people smarter.

Medical Apartheid Essay Example | Topics and Well Written Essays - 500 words

Medical Apartheid - Essay Example Admittedly, remedial steps are being taken on the government level to counter barriers mentioned above.A study was carried out by the National Institute of Health to recheck why disparity occurred in this drug’s efficacy for blacks and Asians but not whites. This research concluded that this was most likely a result chance. Even if there was a small possibility that this drug actually did hold some hope for HIV patients, especially blacks, it definitely called for further research and testing. The reason mostly given for not carrying out further research is that blacks are resistant to being subjects for testing, especially for HIV. However, many researchers have been successful in recruiting a large number of blacks for their work. This clearly implies that there is need for more trust and empathy for blacks to cooperate. It is the right of the African Americans to have more research conducted into AIDSVAX as they do represent the majority of sufferers of this disease. Furthermore, if this drug does indeed prove to be primarily applicable to blacks, these differences will most likely be environmental; even if the differences are determined to be somewhat racial, one successful drug could be made adaptive to whites with further work. The world indeed sits in wait of a miracle drug that could cure the ‘incurable’ AIDS. So far, AIDSVAX is the only drug that has come closest to being it. Our country has a battle with itself right now of overcoming this discrimination against race and color for common good.
