Get priceApr 24, 2013 · Steel is made in a subsequent process as an alloy of iron and carbon (along with some other elements). Around 1% of the carbon from the coke remains in the raw iron to provide the source of that carbon. So coal (as coke) is a reducing agent, a source of energy to drive the process and a source of carbon to incorporate in the steel.

This smelting process melts out and separates iron from the original rock material. Iron ore is mixed with coke, a form of very pure coal. The blast furnace burns the coke to heat the iron ore causing it to react into iron (Fe 2), nitrogen (N 2), and carbon dioxide (CO 2). This iron is often known as "pig iron" or "hot metal" as it is a liquid
