Steel Slag - an overview | ScienceDirect Topics
Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process. In the primary process, crude steel is produced in two ways.
