摘　　要：首钢贵阳特殊钢有限责任公司通过采用"60tConsteel EAF→LF→VD→CC"工艺流程,对低碳快削钢进行化学成分和精炼渣冶金效果优化,成功开发出化学成分稳定、夹杂物分布均匀和切削性能优良的低碳复合型快削钢。工艺优化后生产的低碳快削钢材料的切削性能指标明显好于优化前,其表面粗糙度达到了0.80μm的水平。Through chemical composition and refining slag metallurgical effect optimization, the low carbon composite fast cutting steel was successfully developed by the ＂60 t Consteel EAF→LF→VD→CC＂ process in Shougang Guiyang Special Steel Co. , Ltd. Results ＇show that the steel chemical composition was stable, the inclusions distributed were uniform and cutting performance was good. The cutting property of low carbon composite fast cutting steel material by the optimized process was much better than that before, the surface roughness had reached the level of 0. 8μm.
