| 摘 要： | S系易切削奥氏体不锈钢303CuS2(%:≤0.08C、8.00～10.00Ni、17.00～19.00Cr、1.50～3.50Cu、0.24～0.35S)冶炼的工艺为60 t EAF-60 t AOD-60 t LF-CC流程。通过将AOD精炼渣的碱度由原先的2.0降至1.6和控制AOD出钢渣量,AOD出钢的S]由0.004%～0.006%提高到0.008%～0.010%,并通过喂含S量50%的S线,控制终点温度,使S的回收率由原先的30%～50%提高到60%～70%,产品合格率由85%提高到100%。

| Abstract: | S-series free-cutting austenite stainless steel 3O3CuS2 ( % : ≤0. 08C, 8. 00 ~ 10. 00Ni, 17. 00 ~ 19. 00Cr, 1. 50 〜3. 50Cu, 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% . |
