The coke is made by pressurizing coal with pulverized coal and other coke materials, and then post-processing by carbonization. Some types of briquettes made by oxidative heat treatment or self-heat hardening are also called coke.
The raw materials are pulverized, ground, added with a binder, and then pressed into a semi-finished type of coke ball by a type of coke ball machine, and then carbonized to form a coke. The coke can be used as a block fuel and gasification raw material for industrial or civil use. Some coke can replace some conventional coke for smelting, chemical, boiler combustion, blast furnace ironmaking or cupola smelting, etc., and can replace coke. Compared with coke, coke has the advantages of low cost, easy processing and transportation.
