Coking coal is mainly used in blast furnace ironmaking and blast furnace smelting of nonferrous metals such as copper, lead, zinc, titanium, antimony, mercury and other nonferrous metals. It plays the role of reducing agent, heating agent and column skeleton. Coke oven coal instead of charcoal is the foundation for the large-scale blast furnace. It is a milestone in the history of metallurgy. In order to achieve better technical and economic indicators for the operation of the blast furnace, the metallurgical coke (metallurgical coke) must have appropriate chemical and physical properties, including the thermal properties of the smelting process.
