Basic introduction metallurgical coke blast furnace coke, foundry coke, ferroalloy coke and non-ferrous metal smelting coke collectively. Since more than 90% of metallurgical coke for blast furnace it is therefore often referred to as metallurgical coke to blast furnace coke. Foundry is dedicated to the molten iron cupola coke. Foundry is the main fuel of the molten iron cupola. Its role is to melt the charge and molten iron overheating, the support material column maintains its good permeability. Thus, Foundry should have blocks of large, low reactivity, low porosity, have sufficient impact crushing strength, low ash and sulfur content. The basic use of blast furnace and coke is mainly used for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal smelting blast furnace, a reducing agent, heating agent and the material column skeleton. Blast furnace using coke instead of charcoal, laid the foundation for large-scale modern blast furnace, it is a major milestone in the history of metallurgy. For the blast furnace operation to achieve better technical and economic indicators, metallurgical coke (metallurgical coke) must have the appropriate chemical and physical properties, including the smelting process of thermal properties. In addition to a large number of coke for iron and non-ferrous metal smelting (metallurgical coke), but also for casting, chemical, calcium carbide and ferroalloy, their quality requirements vary. Such as foundry coke, general requirements for large size, low porosity, high fixed carbon and low sulfur; chemical coke gasification, strict requirements for strength, but requires that the reaction is good, high ash melting point; carbide production coke requirements maximize the fixed carbon content. .
