To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added. In fact, a very simple definition of steel is "iron alloyed with carbon, usually less than 1%." The following text is taken from the Structural Manual For Ironworkers Manual V-Volume I. ...

This is the most refined metal that can be made from iron. Most of the impurities are removed from the iron and it becomes a much stronger metal. There are several methods to make steel.
Details
1 Molten steel is made by melting iron ore and coke (a carbon-rich substance that results when coal is heated in the absence of air) in a furnace, then removing most of the carbon by blasting oxygen into the liquid. The molten steel is then poured into large, thick-walled iron molds, where it cools into ingots.
Details
The coke is mixed with iron ore and limestone to make molten iron, which is then further treated and heated to make steel. Generalized diagram showing how steel is made. In the steel-making process, coke is used in the blast furnace as a (1) fuel to produce added heat; (2) chemical-reducing agent for the reduction of iron oxides; and (3) as a ...

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.
