本发明涉及一种转炉冶炼回炉高硅钢水的方法，转炉中兑入回炉高硅钢水，再兑入铁水至预定装入量，使转炉中的钢水硅含量≤1.0％；转炉采用双渣冶炼的方法，加入的造渣料包括活性石灰、白云石、轻烧白云石、烧结矿；吹炼时氧累达到83％‑85％时使用副枪测量TSC，按TSC测量数据吹炼至钢水目标成分和目标温度后提枪，出钢。本发明实现转炉冶炼回炉高硅钢水的稳定控制。降低钢厂经济损失，减少炼钢生产事故率。提高了炼钢生产作业率。

本发明公开了一种无取向电工钢清洗工艺，包括以下步骤：1)在脱脂剂箱体中添加脱脂剂溶剂，通过喷射泵将脱脂剂分别从上下两路管道喷出，经过流量控制电磁阀进入喷射梁，通过喷嘴喷洒在带钢表面；2)带钢轧制后温度为100～150℃，速度为600～1000m/min，带钢表面高温确保脱脂剂与带钢表面残留油脂反应充分，且在高速下喷射的脱脂剂与带钢相向而行，使带钢表面反应后残留硅泥、铁粉被迅速带走；3)喷射后的脱脂剂流入收集槽中，通过泵重新打入脱脂剂箱体中，实现脱脂剂的循环利用。其利用轧制时产生的高温及高速对带钢表面残留乳化液斑迹、铁粉、硅泥进行清洗，清洗彻底高效。
