Hot sale calcined Pitch Coke 98.5% carbon
Coke are made from a mixing material of serval kinds of coal,under a high temperature(1300ºC) process.They are widely used for steelmaking,ferroalloys manufacture or non-ferrous metals smelting,iron castings manufacture or other related metallurgical and foundry industry,because of its special physical and chemical characteristics:high strength and fixed carbon content,low sulfur and low volatile matter content.
Coke is a kind of additives used in steelmaking, casting, is an essential part of raw materials, production of high quality steel electrode paste are in addition to production of raw materials. Recarburizer there are many kinds of raw materials, production process is different, have wood carbon, coal carbon, coke, graphite, etc, among them under various classification and there are a lot of small type. High quality recarburizer generally refers to after graphitization of carburant, under the condition of high temperature, carbon atoms arranged in the microstructure of graphite, so called the graphitization. Graphitization can lower the content of impurities in the carburant, improve the carbon content of carburant, reduce sulfur content; Apply to cast iron (steel) and carbon, grey iron casting high carbon, low sulfur, low water content and the characteristics of low cost and high cost performance.
1.Coke 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.Coke is for casting and copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal blast furnace smelting, from the reducing agent, heat agent and the role of column skeleton.
3.In 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.
