6: Manufacture of Iron and Steel Flashcards

In its initial state, pig iron is a rather useless material with essentially no product value. It is hard, brittle, and not very strong. However, it is vitally important in the manufacture of steel. Cast iron foundries (and some steel foundries) purchase pig iron and melt it in induction furnaces or cupolas to make cast iron. 2.
