- 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: 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: What is the essential difference between coal and coke?
- Coke]Coke is bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage is made, the process is called high temperature coking (high temperature carbonization). Coke obtained from high temperature coking for blast furnace smelting, casting and gasification. 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.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. 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 are the requirements for the quality of coke in blast furnace smelting
- Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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.
- Q: The cost of iron ore and coke
- At present the general level of building materials enterprises, the price of 2400 yuan / ton steel
- Q: Coke crushing, coke plant equipment, coke jaw crusher, coke crushing equipment prices, manufacturers offer? How is the output of these equipments?
- The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke)
- Q: What are the quality indicators of coke
- Coke is a solid product of high temperature carbonization, the main component is carbon, is a crack and irregular pore structure (or porous). The number of cracks has a direct impact on the strength and crushing strength of the coke, the index is generally measured in terms of crack degree (the number of cracks in the unit volume coke). 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.
- Q: Distinction and distinction of cokeSoil coke, improved coke, coke machine coke do, what is the difference between
- The concept of coke:Bituminous coal in the absence of air is heated to 950-1050 DEG C, after drying, pyrolysis, melting, bonding, curing and contraction of the final stage of this process is made of coke, coking high temperature (high temperature carbonization). By high temperature coking coke for blast furnace smelting, casting and gas generated in the process of coking. After the recovery and after the purification of coke oven gas is not only a high calorific value of fuel, and is an important raw material for organic synthesis industry. Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% were used for blast furnace ironmaking blast furnace coke, so often referred to as metallurgical coke is coke. The special cupola molten iron and coke. Coke is the main fuel cupola molten iron. It is melting charge and molten steel overheating, the support column to maintain its good permeability. Therefore, coke should be Preparation of large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- 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.
- Q: What is the difference between coke and coking coal
- Metallurgical coke is coke, coke, iron alloy coke and non-ferrous metal smelting coke for metallurgical coke collectively. More than 90% are used in blast furnace, the furnace coke often called metallurgical coke. Metallurgical coke quality standard Chinese formulation (GB/T1996-94) is the blast furnace quality standards.Gasification coke is a kind of coke, which is specially used in the production of gas. It is mainly used in the fixed bed coal gas producer with solid slag discharging. It is used as the raw material to produce CO and H2 gas
