分析了本钢采用转炉→炉外精炼(LF+RH)→矩形坯连铸工艺流程生产齿轮钢控制钢中T[O]含量的工艺流程,并提出转炉复吹、精炼LF白渣操作、RH真空循环及钙处理是降低钢中T[O]含量的关键。
The technological process of T [O] content in gear steel for controlling steel production by gearbox → LF + RH → rectangular billet continuous casting process was analyzed and the operation of BOF blowing, refining LF white residue, RH Vacuum cycle and calcium treatment is the key to reducing T [O] content in steel.
