Steel Slag an overview ScienceDirect Topics

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. In the first method, the iron is produced from ore in the BF, thus, generating BF slag BFS. BBOF slag BOFS is produced in the steelmaking process by using the molten iron coming from the BF.
