Contact SupplierPig Iron is raw iron, the immediate product of smelting iron ore with coke and limestone in blast furnace. Pig Iron has a very high carbon content, typically 3.5%, which makes it very brittle and not useful directly as material except for limited application. Merchant pig iron comprises three main types: BASIC PIG IRON, used mainly in electric arc steelmaking, HAEMATITE PIG IRON [also known as Foundry Pig Iron], used in mainly in the manufacture of grey iron castings in cupola furnaces, and NODULAR PIG IRON, used in the manufacture of ductile [also known as nodular or spheroidal graphite - SG] iron castings. Pig iron contains at least 92% Fe. Other constituents are typically: The vast majority of PIG IRON is produced and consumed within integrated steel mill complexes. In this context the term “pig iron†is something of a misnomer: within integrated steel mills, blast furnace iron - hot metal - is transferred directly to the steel plant in liquid form. The term “pig iron†arose from the old method of casting blast furnace iron into moulds arranged in sand beds such that they could be fed from a common runner. The group of moulds resembled a litter of sucking pigs, the ingots being called “pigs†and the runner the “sow.â€
