Coke making is effectively the carbonization of coal at high temperatures. Production normally takes place in a coke battery located near an integrated steel mill. In the battery, coke ovens are stacked in rows. Coal is loaded into the ovens and then heated in the absence of oxygen up to temperatures around 1,100 degrees Celsius (2,000 degrees ...

Steel production - Coal is crucial to steel production, particularly in the form of coke, a high-carbon, low-impurity fuel. In steelmaking, coke serves as a reducing agent in blast furnaces, facilitating the conversion of iron ore into iron. It also provides the required heat for the smelting process. The steel industry's reliance on coal makes ...
