How is Steel Made? Steel Production Process (With PDF)
To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make steel. Modern-day steel making is highly improved and specialized. There are two processes that are widely popular for modern-day steel making. They are:
