Coke is coal in isolation under the conditions of high temperature air dry distillation get of the product.
Main purpose: It is widely used in iron and non-ferrous metal smelting, casting, chemical industry, calcium carbide and ferroalloy, etc.
Metallurgical coke is produced by carbonization of coals or coal blends at temperatures up to 1400K to produce a macroporous carbon material of high strength and relatively large lump size.
Metallurgical cokes must have a high strength to support heavy loads in the blast furnace without disintegration. Metallurgical coke is also used as filler coke for polygranular carbon products.
- Q: Various types of coal coke are the main test items
- If you need to test coal, caking index (G value), glial layer (X, Y) and other indicators, the index also includes the detection of more coal ash melting point (ash melting), hydrocarbon, the Hardgrove grindability index of coal, burning, swelling, activity, Oaxaca coal coal. Slag index.
- 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: What is the difference between coking coal and coke
- Therefore, coke is not coking coal, coking coal is one of the products after processing
- Q: Who knows the proportion of pig iron and coke used in Cupola
- Raw material inputs: the main raw material for casting pig iron, scrap steel, manganese, etc.. Under normal circumstances after the melting of ordinary cast iron scrap iron and scrap steel ratio of 9:1 or so, the drying enterprises use pig iron and scrap ratio of about 6:4, according to the requirements of the product. Because pig iron and scrap carbon content is not the same, the higher the carbon content of pig iron is about 4 ~ 4.3, low carbon steel scrap, about 0.8.
- 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 is the phosphorus content in coke
- Generally, the phosphorus content of coke is low, about 0.02%.The bituminous coal is heated to 950-1050 DEG C under the condition of air isolation
- Q: What are the ingredients of coke
- 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.Coke is a special and molten iron cupola coke. Coke is the main fuel cupola molten iron. Its role is to melt the burden and make the hot metal overheating, the support column to maintain good ventilation. Therefore, the foundry coke should have large blocks, low reactivity, porosity is small, with impact crushing strength, low ash and sulfur enough.
- Q: Why in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produceWhy in the blast furnace ironmaking with coke instead of charcoal why coke can produce heat to improve the heat of the furnace how to produce
- Under the condition of isolated air, the bituminous coal is heated to 950-1050 DEG C, and finally, the coke is made by drying, pyrolysis, melting, bonding, solidification and shrinkage
- 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: How many degrees of coke ignition temperature can ignite coke
- The average specific heat capacity is 0.808kj/ (KGK) (100 DEG C), 1.465kj/ (KGK) (1000 DEG C);The thermal conductivity is 2.64kj/ (MHK) (room temperature), 6.91kg/ (MHK) (900 DEG C);Ignition temperature (450-650) in air;
