Coke Oven Gas Generation and Usage IspatGuru

Coke is an essential input for the ironmaking process. For making coke, coal is heated in the absence of air to drive volatile matter (VM) from it. Conversion of coal to coke is called coal carbonization and the process is carried out in coke ovens. A coke oven battery consists of a number of coke ovens.

How does coke and coal play into steel making?

Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.
