Q: What is the density of coke?: There is also a parameter is also available for your reference: coke porosity of 35% ~ 55%The above parameter is a general range, according to the need to choose to determine.

Q: Coke is how to produce, what is its purpose?: Under the condition of air isolation, the bituminous coal is heated to 950-1050 DEG C, which is finally made into coke by drying, pyrolysis, melting, bonding, solidification and shrinkage. Coke oven gas produced in the process of coking and recovery is not only a high calorific value of fuel, but also an important industrial raw material for organic synthesis.

Q: Coke belongs to the coal industry: Warehousing and postal 03 animal husbandry 26 chemical raw materials and chemical products 51 railway transportation 04 fishery 261 other chemical materials 52 road transport 05 Agriculture Forestry Animal Husbandry and fishery service 262 fertilizer 53 city public transportation B mining 263 pesticides 54 Water Transport 06 coal mining and washing industry 264 coatings, printing ink, pigment and similar products 55 air transport 07 oil and gas pipeline transport 08 5600 265 synthetic materials of ferrous metal ores 266 special chemical products 57 loading and unloading and other transport 09 non-ferrous metal mining 267 daily chemical products 5710 handling 10 non metal mining 27 medicine manufacturing 5720 transport agency services

Q: What are the indicators of first grade coke and the two grade coke?: The mechanical strength of the mechanical strength of ash sulfur%% volatile(crush strength M40) (abrasion strength M10)

Q: What is the reasonable standard of volatile content of coke: Generally speaking, the volatile content of coke is about 1.5 or so, but not more than 2

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?: Coke:The utility model is mainly used for blast furnace ironmaking and smelting of blast furnace for non-ferrous metals such as copper, lead, zinc, titanium, antimony, mercury, etc.. 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: With the number of 1 tons of steel smelting coke: The use of coke pig iron smelting blast furnace, for each different, which is each blast furnace coke ratio (the ratio of the iron smelting a ton of coke by iron determined how many meals). The country or the world, the iron and steel enterprises coke are not the same, the coke rate is as low as possible, but there are many factors which restrict the level of coke, such as advanced level equipment, raw material and fuel quality, or the operator level, advanced process and so on many factors which influence

Q: The sulfur content of coal and coke in general, the coking process of sulfur content of coal into the output of sulfur content of coke compared to those who are high and low?: The sulfur content of coking coal basically all into the coke, only a small number into the gas but the number is very limited. How much coal is the amount of sulfur in the general coal is the sulfur. It should be said that coke is basically a little lower and a little bit limited.In the process of coking volatile will be a lot of consumption, ash will increase 2-3%.

Q: Coke in the whole process of steelmaking in the end is what to do, just to provide heat or carbon and other substances into steel or iron?In the study of coal classification inside, one is divided into coking coal, coking coal and coke as main, and then you see is steel or iron coke must material. What is not clear. In the end, out of coal mining is mainly used to burn energy extraction, or said that coal like oil can be converted into other products, which is a coke can convert?: It is necessary to add coke, pellet, sinter ore, ore and other materials into the blast furnace in a certain proportion, batch and sequence, and then to produce molten iron in the reducing atmosphere of the blast furnaceAfter the hot metal to steel in converter against the general converter, scrap also need to add a certain amount of used to balance the heat. Hot metal and scrap are added to the converter after the oxygen lance for oxygen operation, the oxidation of oxygen to carbon in liquid iron, silicon, manganese, phosphorus, sulfur and some non-metallic inclusions to form steel. Adding lime, dolomite, iron oxide and mine slag and coolant is needed in oxygen at the same time. After the completion of steel smelting in the tapping process according to different requirements with the corresponding iron alloy steel, after also refining process.

Q: What are the national standards for grade two coke?: Two national standards for metallurgical coke: total sulfur: 0.61 - 0.80; ash: 12.01 - 13.50
