History and Importance of Pig Iron
Pig iron is formed as a result of the smelting of iron ore in a blast furnace. With the help of dolomite and limestone, the coke reduces the iron ore as a flux for eradiing the impurities. The resultant liquefied iron is then cast in the pig machine, which results in the production of pig iron. Pig iron is produced in two egories, to ...
Blast furnace process
21/06/2018 · However, the demand for grey pig iron accounts for only a small part. More than 90 % of the pig iron is beeing tapped as white pig iron ("steel pig iron") and processed in liquid form in ironworks to the actual steel by special aftertreatment processes. These processes are described in more detail in the following articles.

The Carburization of Pig Iron
The formation process of pig iron is mainly the process of gradually melting other alloying elements and carburizing into the reduced metallic iron. In the upper part of the blast furnace, part of the iron ore is reduced to metallic iron when it is solid, and gradually reduced from more iron as the temperature rises.
Iron Ore
Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking.
