分析和研究了105炉SCM318H、SCM322H、SCM420KC、SCM822H、SCr420K等汽车用低碳齿轮钢的20tLFVD精炼终渣碱度、终Al含量和真空时间对钢中氧含量的影响。实践操作结果表明
采用白渣操作
控制终渣碱度不低于3
终Al含量≥0.22%、真空处理时间不低于25min
可使低碳齿轮钢的氧含量稳定地≤15×10
-6
平均氧含量为11.58×10
。
The effect of end slag basicity
end Al content and vacuum treatment time in 20t LF-VD refining on oxygen content in 105 heats gear steels SCM318H
SCM322H
SCM420K-C
SCM822H and SCr40K for auto has been analyzed and studied. The practice operation results showed that using white slag operation
controlling end slag basicity no less than 3
end Al content in steel ≥0.22%
vacuum treatment time ≥25 min
the oxygen content in low carbon gear steel was definite ≤15×10
the average oxygen content in steel was 11.58×10
