WebIn 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. WebFeb 13, 2024 · The concept of “basicity ” has been central to our understanding of slag chemistry for many decades. Traditionally, basicity has been connected to the level of networking present in a slag, acid slags having a great deal of networking and basic slag …
WebSlag basicity is defined as the (CaO% + MgO%)/SiO 2 % ratio of the liquid. If this ratio exceeds 1, the slag is basic; if it is less than 1, it is acidic. Basic slags can be obtained by …
