Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7%, [1] along with silica and other dross , which makes it brittle and not useful directly as a material except for ...
Overview. 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. Charcoal and anthracite are also used as fuel and reductant. Pig iron is produced by smelting or iron ore in blast furnaces or by smelting ilmenite in electric furnaces .

Pig iron, known also as crude iron, is produced by the blast furnace process and contains up to 4–5% carbon, with small amounts of other impurities like sulfur, magnesium, phosphorus, and manganese. Pig iron is supplied in a variety of ingot sizes and weights, ranging from 3 kg up to more than 50 kg.
Dec 15, 2023 · The meaning of PIG IRON is crude iron that is the direct product of the blast furnace and is refined to produce steel, wrought iron, or ingot iron.
For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.
Pig iron of a type used to make ductile iron, stored in a bin. Pig iron is iron with a high carbon content. Pig iron is made by smelting iron ore into ingot form, in a blast furnace. It’s called pig iron because when being cast, each ingot being cast looks like a Piglet suckling milk from a sow.
