Steel Pig Iron - product info

Steel Pig Iron: Pig iron is the intermediate product of smelting iron ore with a high-carbon fuel such as coke, usually with limestone as a flux. Pig iron has a very high carbon content, which makes it very brittle. Pig iron is typically poured directly out of the bottom of the blast furnace through a trough into a ladle car for transfer to the steel mill in mostly liquid form, referred to as hot metal. The hot metal is then charged into a steelmaking vessel to produce steel, typically with an electric arc furnace or basic oxygen furnace.
