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. Announcing our NEW encyclopedia for Kids! Egnaledknarf. 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 weights. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... …blast furnace became known as pig iron from the method of casting, which involved running the liquid into a main channel connected at right angles to a number of shorter channels. The group of moulds resembled a litter of sucking pigs, the ingots being called “pigs” and the runner the “sow.”. 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. Pig iron contains at least 92% Fe and has a very high carbon content, typically 3.5 - 4.5%. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Charcoal and anthracite are also used as fuel and reductant. See cast iron. Other constituents are given in the table below: Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg. 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.
