摘要
通过优化电炉出钢喷炭粉、调整脱氧制度、选择合适时机的钙处理、采用合理的调硫工艺等一系列措施．经“UHP＋IJ＋VD＋CC”工艺流程，批量生产出全氧质量分数≤20×10-6,硫化物夹杂级别≤2．0级的汽车用含硫齿轮钢fS含量范围在0．017％-0．035％）。
By taking a series of measures such as spraying carbon powder during EAF tapping, adjusting deoxydation process, calcium treatment at appropriate stage, reasonable sulfur adjustment process and stirring before casting, The sulfur-beating pinion steel for automotive with total [O]≤20×10-6 and sulfide inclusion ≤2.0 was produced through ＂UHP＋LF＋VD＋CC＂（sulfur content was controlled within 0.017%-0.035%）.
