feeding sulphur wire and deoxidation process for a 45 t LF on control of sulphur
oxide content and sulphide in steel 28MnCr5(0.25~0.30C
0.60~0.80Mn
0.020~0.035S
0.80~1.00Cr) have been tested. Results showed that as feeding sulphur wire with basicity of LF refining slag-2.8~5. 1
the yield of sulphur after VD was up to 80%~90% and oxide rating in steel≤1.5;and feeding suitable amount of CaSi wire was available to improve the morphology of sulphide in steel.
