Q: What are the companies that produce coke: Too many enterprises to produce coke. You search on Baidu, coke, a lot of business

Q: Coke can be used to do what carbon black can be used to do?: 1 coke is used to restore the iron ore, coal through pressure, isolated air and high temperature dry distillation, and the by-product of coal gas and coal tar is an important chemical products;

Q: What is the concept, relationship and difference between coke and coke? The main difference and contact, thank you: Formed coke is a product obtained through several steps:(1) environmental protection continuous high efficiency carbonization furnace(2) the use of anthracite powder to produce plastic molding coke and supporting technology(3) a new type of environmentally friendly carbonization carbonization furnace without three wastes discharge.(4) hydraulic press

Q: Coking coal, coke, coal, steam coal what is the difference?: Coke is used for blast furnace ironmaking and iron ore in the steel furnace to play the role of the heating skeleton to support reducing agent

Q: What are the uses of these early industrial iron and steel? Any difference?What kind of carbon do we eat in the middle of a long strip of carbon?: Charcoal:1 metallurgical industryIn the past, the charcoal was used to smelt iron ore, and the pig iron was melted by charcoal and coke. The structure and mechanical properties were not the same even if the chemical composition was the same. The charcoal smelting pig iron generally has the fine grain structure, the casting is compact, does not have the crack the characteristic, the pig iron with the charcoal production contains the impurity is few, is suitable for the production high quality steel. Due to the reduction of charcoal, so in the metallurgical industry can be used to restore ore smelting metal.In the non-ferrous metal production, charcoal used for surface flux, non-ferrous metal melting, the surface flux in the molten metal surface protective layer, so that the separation of metals and gases, can reduce the loss of molten metal splash, and can reduce the melting material in gas saturation.A large amount of charcoal is also used to produce crystalline silicon, silicon used charcoal ash production should not contain too much carbon and head.

Q: What are the ingredients of coke: Two, coke distributionAccording to the distribution of coke production in China, the geographical distribution of coking enterprises in China is unbalanced, which is mainly distributed in North China, East China and northeast china.Three, the use of cokeCoke is mainly used in blast furnace ironmaking and smelting of non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury and so on. The use of coke instead of charcoal in the blast furnace has laid the foundation for the large-scale development of modern blast furnaces and is a major milestone in the history of metallurgy. In order to achieve better technical and economic indexes of blast furnace operation, the coke (metallurgical coke) must have proper chemical and physical properties. In addition to a large number of coke used in iron smelting and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and iron alloy, the quality requirements are different. 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.

Q: Do not understand why some of the indicators of coke is the cause of the full analysis of phosphorus or foundry use of this time?It is best to use the foundry requirements? Thank you: Phosphorus is a kind of harmful element in metal, which reduces the mechanical properties of castings. Under normal circumstances, GB castings of phosphorus content requirements of less than 0.06%, the lower the special requirements

Q: What does the M40% and M25% mean in the analysis of coke?: (1) crushing strength (shatter strength): the ability of a certain particle size coal sample to fall under the condition of free fall.

Q: Natural gas can replace coke smelting pig iron: Coke at high temperature (also some blast furnace pulverized coal, heavy oil, natural gas and other auxiliary fuel) in carbon with bubbling air oxygen in the combustion of carbon monoxide and hydrogen generated in the furnace, removing the rise in iron ore in the process of oxygen, thereby reducing iron. The molten iron is released from the taphole. An iron ore, which is a mixture of non - reducing impurities, such as limestone, to form a slag from the slag. The produced gas is discharged from the top of the furnace, and is used as a fuel for a hot blast stove, a heating furnace, a coke oven, a boiler, etc.. Blast furnace smelting is the main product of pig iron, as well as by-products of blast furnace slag and blast furnace gas.

Q: How much coke is needed for a ton of iron: 1 tons of iron: iron ore + + coke 340kg + pulverized coal injection 130kg,The process of extracting iron from iron containing minerals, mainly iron oxides, is mainly composed of blast furnace, direct reduction, smelting reduction and plasma method. From the perspective of ironmaking is metallurgy, iron rust, inverse behavior gradually mineralized, simple, pure iron reduction from iron compounds. Pure iron is not common in actual production. More iron carbon alloy.
