1, is the most important product of coking, most countries more than 90% of the coke for blast furnace ironmaking, iron smelting coke instead of charcoal, for the modernization of large blast furnace laid the foundation for metallurgy history is a major milestone.
2, for casting and copper, lead, zinc, titanium, antimony, and other non-ferrous metal blast furnace smelting, from the reducing agent, heat agent and the role of column skeleton.
3, smelting industry, a small amount for the preparation of calcium carbide, carbon disulfide, phosphorus and other elements. In steel joint ventures, coke powder is also used as sintered fuel. Coke can also be used as a raw material for the preparation of water gas to prepare raw materials for synthesis.
4,in order to achieve a better technical and economic indicators of blast furnace operation, smelting coke (metallurgical coke) must have the appropriate chemical properties and physical properties, including the thermal properties of the smelting process.
5,coke in addition to a large number of iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferroalloy.
It may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel, for its calorific value may achieve above 9386K/KG. It may substitute burnt carbon massively. The burnt carbon exportation needs the quota; Therefore the carburizing agent price superiority is similarly obvious.
