Metallurgical Steel


Metallurgy is a process in which impurities (unintended elements) in a metal solution are melted (heated to above the melting point) for slagging and slag removal. At the same time, some chemical components are obtained by slag removal, decarburization and oxygen removal to obtain relatively pure alloy components.
