Q: The chemical composition of coke is m10.m25: Quality index of cokeThe quality index of coke coke [] is a solid product of high temperature carbonization, the main ingredient is carbon, is the pore structure has a crack and irregular (or pore porous). The crack number directly affects the coke strength and crushing strength, the index of general degree (refer to how to crack crack length unit the volume of coke in the measure.) to measure the pore structure of the main indicators for the porosity (coke pore volume only percentage of the total volume) that it affects the coke reactivity and strength

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: Coke indicators are divided into grades: The index of pore structure is mainly expressed by the porosity rate (the percentage of the total volume of coke), which affects the reactivity and strength of coke. Different uses of different coke porosity index requirements, the general requirements of metallurgical coke porosity in the 40 ~ 45%, 35 ~ 40% in coke, coke export demand in about 30%. Coke crack degree and the porosity level, and the coking coal has a direct relationship, such as coal based coke refining, crack, high porosity, low strength; with coal as the foundation of the coal refining coke crack less, low porosity and high strength

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?: In addition to the reaction of iron and iron oxide will react C+O2=CO2; reaction exothermic;

Q: What is the amount of waste gas produced by a ton of coke burning: The coking coal is heated to 1000 DEG C under the condition of isolated air (high temperature carbonization)

Q: What's the connection between coking coal and coke: The coke can be obtained with the advantages of large grain size, few cracks and high crushing strength, and the abrasion resistance is good. But the expansion pressure, the coke pushing difficulties must be allocated to coal, lean coal, in order to improve the operating conditions and improve the quality of coke. Coking coal can play the role of coke skeleton and relieve shrinkage stress, so as to improve the mechanical strength of coke.

Q: What is the difference between the industrial analysis of coke and the industrial analysis of coal samples: Quite a lot! You'd better look at the standard coal GB/T212-2008,

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: What does the M40% and M25% mean in the analysis of coke?: M40% and M25% represent the breaking strength rate, 40%>25%, which means that the M40% coke is more resistant than M25%

Q: The coke is divided into several separate uses: Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke ". Since more than 90% of metallurgical coke is used for blast furnace ironmaking, it is often referred to as coke. The metallurgical coke quality standard (GB/T1996-94) developed in China is the quality standard of blast furnace.
