Steel can also be made in an electric arc furnace (EAF) from scrap steel and, in some cases, from
Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.
How to make steel. At the most basic, steel is made by mixing carbon and iron at very high temperatures (above 2600°F). Primary steelmaking creates steel from a product called "pig iron.". Pig iron is smelted iron, from ore, which contains more carbon than is correct for steel. The steelmaker uses a system that bubbles oxygen through ...
