Application
mainly used in aluminium metallurgy,aiso used in abrasive ,cement ,chemical, refractory
- Q: Standard grade two grade coke standard
- Quality index of cokeCoke 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. 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. The strength of coke is usually represented by two indices of crushing strength and abrasion resistance. Coke crushing strength refers to coke can resist foreign impact force without ability along cracks or defects at the broken, represented by the M40 value; wear strength of coke coke refers to the ability to resist external friction without surface of glass forming debris or powder, said M10. The cracking degree of coke affects the M40 value of its breaking strength, and the pore structure of coke affects the M10 value. There are many methods for determination of M40 and M10 value method, commonly used in our country the German migon drum test.
- 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
- To be exact, you don't need coke for steelmaking, you say that it's iron making
- Q: Coke is divided into several kinds of specifications ah
- Three: 1 2 3 coke metallurgical coke of high sulfur cokeCoke is in coal under the condition of air isolation, heating 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.
- Q: What is the difference between coking coal and coke
- Coking coal is the raw material for producing cokeCoking coal is produced by carbonization: coal gas (carbon monoxide), coal tar, coke
- Q: Coke indicators are divided into grades
- 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).
- Q: How coal is turned into coke in the coking chamber
- In the furnace in the absence of air through the kiln wall edge ignition hole artificial ignition, coking coal will be stacked in the kiln fire, coking coal self combustion heat by layer coal heating (direct fire heating); a large amount of coal gas from coal combustion and unburned cracking formation hot air flow,
- Q: Some experimental results summarized the following two facts: the coke can not be used to restore aluminum mine, but it can be used for the reduction of copper and iron; no containing copper sulfate solution with tin, thus the activity sequence C, Al, Cu, Fe of the four elements is ______.
- Coke can not be used to restore aluminum ore, but can be used to restore copper and iron ore, indicating that aluminum is the most active
- 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: What is coke and how is coke classified?
- Types of cokeCoke is usually divided by use of metallurgical coke (including blast furnace coke, coke and iron alloy coke, calcium carbide and coke gasification etc.) with coke. The pressurized pulverized coal forming coal, coke carbonization etc. in the new postprocessing process called Formcoke.
- Q: What is coke? What is the use?
- The use of coke coke is mainly used in blast furnace and used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting of blast furnace, reducing agent, heating agent and columnar skeleton blast furnace adopts coke instead of charcoal.
