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: The chemical composition of coke is m10.m25: Abrasion resistance refers to the ability of coke coke can resist friction without generating surface of glass forming debris or powder, by the M10 value. The effect of the crack of coke crushing strength, M40 value, the influence of coke pore structure of abrasion strength M10 value determination method of.M40 and M10 was more in China the migon drum test in Germany. As shown in table 31-1.After the completion of the test, the sieve with the pore diameter of 40mm and 10mm screening, greater than the percentage of 40mm particle size is M40, less than 10mm of the particle size of the M10 value. The intensity of the provisions of China Metallurgical Coke indicators are shown in table 31-2.

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?: Generate CO2;Of course, high temperature will produce CO, but not many;Please ask questions

Q: How to distinguish the level of coke. What is metallurgical coke: The utility model is characterized in that the coal is formed by the compression of the coal powder, and a new type of coke, which is processed after carbonization, is called a coke. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke "

Q: What are the requirements for coke and other accounts?: Futures account opening process1, customers need to carry the original natural person identity card or temporary identity card (must be within the validity period), at least any one settlement bank (China bank, agricultural bank, industrial and commercial bank, construction bank, Bank of Communications) debit card or passbook, to the Futures Company branch or the securities business Department (IB) personally.2, the signing of the "futures trading risk statement", "futures brokerage contract", "bank transfer", "letter of credit" and other agreements, to provide the phone, contact address and postal code.

Q: I now do a good job in the coke network editor, I would like to know more about coke: Coke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. In the process of blast furnace smelting, there are four kinds of functions, such as heat supply, reduction, material skeleton and carbon supply.

Q: The chemical composition of coke m10.m25 refers to?: 1, coal washing ((M25 drum index) metallurgical coke crushing strength is (M10 drum index) metallurgical coke wear strength is reflected

Q: The cost of iron ore and coke: The full cost of 2300 yuan / ton, manufacturing cost of 1950 yuan / ton, the use of iron ore per ton of steel 1.6 tons

Q: What is the effect of coke moisture on the blast furnace?: 2, if the long-term use of water containing high coke and blast furnace gas purification system and dry, it will affect the normal operation of the purification system (filtration pressure increased, serious and even lead to normal filtration, also lead to dust can not be normal unloading etc.); more serious for the blast furnace with net gas said not even a normal discharge (top pressure tank or a pressure higher than indoor clock dozens of kPa

Q: What is coke? What is the use?: In addition to coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, its quality requirements vary. Such as foundry coke, generally require large size, low porosity, high fixed carbon and low sulfur; chemical gasification, strict requirements for strength. But requires good response, high ash melting point; calcium carbide and coke production requirements to improve the fixed carbon content.
