Pig iron is a raw material produced from the smelting of iron ore in a blast furnace. It typically contains around 3-4% carbon, along with varying amounts of other elements such as manganese, silicon, sulfur, and phosphorus. The name "pig iron" is derived from the traditional method of casting iron into molds that resemble a sow and her piglets. Pig iron is an intermediate product in the production of wrought iron and steel.
