Pig iron: definition, applications, properties ...

Properties of pig iron. Pig iron is also known as crude iron. It is obtained from a smelting furnace in the form of oblong blocks and has a very high carbon content of 3.5 – 4.5 as it contains 90% of iron. It is produced by smelting iron ore with high-carbon fuel and reductant such as, coke usually with limestone which serves flux.
