Pig Iron

Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel, which is developed by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7% along with silica and other constituents of dross, which makes it brittle and not useful directly as a material except for limited applications. Pig iron is preferred to be refined by steel producers before steelmaking processes. Other sectors prefer buying it as is for their sole purposes. Customers must specify the size of pigments for casting of pig iron.
