Q: Standard grade two grade coke standard: Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.

Q: What does Coke test index M25 mean?: . Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10, our method using migon drum test in Germany.

Q: Coke is how to participate in the steel, and the pellets, sintering, a piece of the furnace in the furnace or in other containers: Molten iron is produced in a reducing atmosphere of the blast furnace, which is then supplied to the steelmaking plant for steelmaking.

Q: Said the details can add points ah: Both are expressed in terms of the crushing strength of the cold mechanical strength index of coke quality.Among them, because of the specific measurement methods are not the same, so the use of different records.

Q: What is the difference between coking plant and coke plant: Never heard of coke plant, coking plant is the production of coke products, there are other chemical products, it is estimated that you said the coke plant is the purchase of other people's desire to sell second-hand coke traders.

Q: How coal is turned into coke in the coking chamber: In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,

Q: What is the difference between coal and coke, heat, price, pollution, smoke, odor. Thank you experts answer: In terms of combustion, coal coke is a high pollution, therefore, coke pollution is less than coal. Coke smoke is very little, the smoke of coal is relatively large, there is also a high quality of soot rarely. When the coal is burning, the smell is bigger and the coke is not completely burnt, so the taste is small.

Q: Why does Coke provide heat when it is fired, it reacts only at high temperatures and why it is needed to provide heat?Which is the exothermic reaction, carbon dioxide or carbon monoxide?: Yes；To restore the Fe reaction to provide heat, this reaction requires a higher heat, but the heat is high, the heat is not high enough to provide; so adding coke, more convenient to raise the temperature;

Q: I see that there are metallurgical coke and coke on the Internet, what is the difference between them (I hope to be able to say in detail) and a level of two points, how is this going on?.. Where is the quality of coke in China? Hunan good coke plant which? Although the problem is a little bit more, I hope that insiders can give some useful information. Extremely grateful.: The following indexes: Metallurgical Coke metallurgical coke: fixed carbon, 86%; calorific value 7300cal/kg; ash < 12%; volatile < 1.9%; all 5% "0.6%" water; sulfur; two metallurgical coke: fixed carbon 84.5-85%; calorific value 7000cal/kg; ash < 13.5%; volatile "1.9% full" water; 6%; "three sulfur 0.7%; metallurgical coke: fixed carbon 83-84.5%; calorific value 6500cal/kg; ash < 15%; volatile < 1.9%; all 6%" 1% "water; sulfur;

Q: What are the requirements for the quality of coke in blast furnace smelting: Evaluation of coke quality1, sulfur content in coke: sulfur is a harmful impurity of iron smelting, which reduce the quality of pig iron. The sulfur content in the pig iron is more than 0.07%. 11% of the sulfur from the blast furnace charge into the furnace comes from the ore, and the other comes from the limestone; the other is from the coke, so the coke is the main source of sulfur in the charge of the 82.5% of the charge. Sulfur content in coke directly affects the production of blast furnace. When the sulfur content in coke is greater than 1.6%, sulfur increased 0.1%, the amount of coke increased 1.8%, limestone amount increased 3.7%, 0.3% increase in amount of ore blast furnace output to reduce the sulfur content under 1.5 - 2.0%. metallurgical coke is not greater than 1%, the use of large and medium-sized metallurgical coke content in blast furnace is less than 0.4 - 0.7%.2, the phosphorus in the coke: iron metallurgical coke coke content should be in the following 0.02 - 0.03%.3, the ash content of coke: Coke Ash on the impact of the blast furnace smelting is very significant. Coke ash increased by 1%, coke consumption increased by 2 - 2.5%, therefore, the reduction of coke ash is very necessary.
