coking coal

Coking coal, also known as metallurgical coal, is a type of coal used primarily in steel production. When heated in a special oven without much air, coking coal transforms into coke—a hard, porous material that acts as a carbon-rich fuel and reducing agent in blast furnaces. The quality of coking coal is crucial because it determines the efficiency and strength of the coke produced, impacting the steel manufacturing process. It is distinct from thermal coal, which is mainly used for electricity generation and does not have the same coking properties.
