How is LD slag produced?

03/01/2014 · Slag is not a random product, but rather a consequence of the LinzDonawitz process, which uses steel as well as LD slag. The slag is separated from the crude steel, separately processed, and its chemical composition analyzed. At the end of the process, the main components of the slag are iron oxide, calcium oxide, and silicon dioxide. Iron and steelmaking are principally subject to permanent ...
