0. 24 - 0. 35S) is smelted by 60 t EAF-60 t AOD-60 t LF-CC flow sheet. With decreasing basicity of AOD refining slag to 1. 6 from original 2. 0 and controlling AOD tapping slag amount
the [ S] in AOD tapping steel increases to 0. 008% ~0. 010% from original 0. 004% - 0. 006%
and with feeding S wire containing 50% S and controling end temperature
the yield of S increases to 60% - 70% from original 30% ~50%
the qualified ratio of products raises to 100% from 85% .
