Metallurgical Coke

Metallurgical coke is a general term for coke used in blast furnace, foundry, iron alloy and non-ferrous metal smelting. Under the condition of air isolated , bituminous coal is heated to 950-1050 C, and the coke is finally made by drying, pyrolysis, melting, bonding, curing, shrinkage and so on. This process is called high temperature coking. Because more than 90% of the metallurgical coke is used for blast furnace ironmaking, blast furnace coke is often called metallurgical coke.
