modern process in pig iron

Pig iron - Wikipedia

Traditionally, pig iron was worked into wrought iron in finery forges, later puddling furnaces, and more recently, into steel. In these processes, pig iron is melted and a strong current of air is directed over it while it is stirred or agitated. This causes the dissolved impurities (such as silicon) to be thoroughly oxidized. An intermediate product of puddling is known as refined pig iron, finers metal, or refined iron. Pig iron can also be used to produce gray iron. This is achieved by remelting pig iron, often along with s

What Is Involved in Pig Iron Production? (with pictures)

Feb 21, 2021  The name “pig iron” comes from the resemblance of the long channel to a mother pig, and the smaller channels to suckling piglets. In most modern pig iron production, however, this process is no longer used, as methods have been developed that allow the pig iron to be transported in a liquid state, rather than as a hard material.
