Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Pig iron is a metal material that results when iron ore, charcoal from coal, and limestone are melted together under intense air pressure.When the combined material cools, it forms a high-carbon product known as pig iron.The cooled material is rarely used by itself, as the large amount of carbon makes the material brittle and unstable. The group of moulds resembled a litter of sucking pigs, the ingots being called “pigs” and the runner the “sow.”. Let us know if you have suggestions to improve this article (requires login).

Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. In this context the term “pig iron” is something of a misnomer: within integrated steel mills, blast furnace iron is transferred directly to the steel plant in liquid form, better known as "hot metal" or "blast furnace iron. The 2” York Olympic Weight Plates are simple yet sturdy. Use of Foundry Pig Iron in Grey Iron Castings. Merchant pig iron comprises three main types: There are also various sub-types, for example low manganese basic pig iron, semi-nodular pig iron etc. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica.

The whole arrangement resembled a sow suckling her litter, and so the lengths of solid iron from the shorter…, Blast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestone. Updates? The moulds were laid out in sand beds such that they could be fed from a common runner. In a random heap, pig iron occupies approximately 50% of … Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces. Charcoal and anthracite are also used as fuel and reductant. This article was most recently revised and updated by, https://www.britannica.com/technology/pig-iron.
