Study of Deoxidization and Desulphurization in Slag Washing Process of Al-Killed Steel

Abstract:

In order to reduce the production cost, In one factory product the SPHC steel of general requirements using slag washing process （BOF→Slag washing oxygen alloying→Ladle argon-blown→CC）, the system study was analyzed about deoxidization and desulphurization behavior of slag washing process. The results of the study show that, when the content of Als 300~500ppm, dissolved oxygen 3~6ppm, the steel desulfurization rate remains stable at 35% to 48%, the average desulfurization rate is 42%. The process of the [N] content, increasing [S] are lower than the LF refining, the operation is simple and can meet the metallurgical requirements.
