Iron and Steel

Iron And Steel

Steelmaking has existed for millennia, but it was not commercialized on a massive scale until the late 14th century. Today there are two major commercial processes for making steel, namely basic oxygen steelmaking, which has liquid pig-iron from the blast furnace and scrap steel as the main feed materials, and electric arc furnace (EAF) steelmaking, which uses scrap steel or direct reduced iron (DRI).
