Steel Slag - an overview ScienceDirect Topics

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. In the second method, slags are generated in the scrap-based steel industry.

Demand for steel, which drives steel production, is a key determinant of energy demand and steel subsector CO 2 emissions. Global crude steel production increased by 5% in 2018 to reach 1 817 Mt, following 6% growth in 2017. Initial estimates suggest 3% growth in 2019. This follows a period of relatively flat demand from 2013-2016.
