摘要
开发Bi易切削钢1215M(%:0.06C、0.04Si、1.25Mn、0.39S、0.17Bi)替代Pb易切削钢SUM24L。生产Bi易切削钢的流程为40t UHP EAF-40t LF(喂Bi线)-180 mm×180 mm连铸-连轧工艺。试验结果表明,Bi易切削钢1215MΦ9 mm盘条夹杂物分布均匀,Bi易切削钢1215M的切削性能优于SUM23HS含S易切削钢与SUM24L含Pb易切削钢相当。
Bi free-cutting steel 1215M （% ： 0. 06C, 0. 04Si, 1.25Mn, 0. 39S, 0. 17Bi） has been developed to replace Pb free-cutting steel SUM24L. The flow sheet for production of Bi free-cutting steel is 40 t UHP EAF- 40 t LF （ feeding Bi wire）-180 mm × 180 mm CC-continuous rolling process. Test results show that the distribution of inclusions in Ф9 mm coil of Bi free-cutting steel 1215M is homogeneous, and the cutting performance of Bi free-cutting steel 1215M is better than that of S free-cutting steel SUM23HS and is equal to Pb free-cutting steel SUM24L.
