Web22 jun. 2016 · 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. WebTo make steel in a blast furnace, coal must first be turned into coke. Coke has a dual role in the steelmaking process.
