Coke in addition to a large number of iron and non-ferrous metal smelting, but also used in casting, chemical, calcium carbide and ferroalloy. The quality requirements vary. Such as casting coke, general requirements of large particle size, low porosity, high fixed carbon and low sulfur content; Chemical gasification coke, the strength requirements are not strict, but require good reactivity, ash melting point is high; Calcium carbide production coke requirements as far as possible to increase the content of fixed carbon.
Coke is divided into metallurgical coke (including blast furnace coke, cast coke and ferroalloy coke, etc.), coke gasification and carbide coke. Coke is mainly used in blast furnace ironmaking and for copper, lead, zinc, titanium, antimony, mercury and other non-ferrous metal blast furnace smelting, reducing agent, heating agent and material column skeleton.
Smelting industry, a small amount of calcium carbide, carbon disulfide, phosphorus and so on. Coke is also used as fuel for sintering in the iron and steel complex. Coke is used as a raw material for preparing water gas to produce raw gas for synthesis.
