摘要
首钢第二炼钢厂通过优化复吹转炉双渣工艺制度,提高转炉前期脱磷效果,在无预处理脱磷设备条件下,可以生产钢材磷含量在0.010%以下的低磷钢,满足钢种对钢质洁净度的特殊要求。
This article describes the practice of dephosphorization process by double slag method in BOF.The result shows that even without hot metal pretreatment equipment we can reduce the phosphorus content below 0.010% in Shougang NO.2 steel making plant and it meets the requirement of pure steel.
