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

Oct 26, 2020· 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.
