120t转炉低硅铁水冶炼实践

摘要

介绍了莱钢炼钢厂120t转炉低硅铁水冶炼工艺。通过优化前期化渣、加入锰矿等手段，可有效解决低硅铁水冶炼成渣困难、不利于脱磷等难题，并在实践中取得了良好效果。%The process of steelmaking with hot metal containing low silicon for 120t converter in LaiWu Steelworks was introduced. Some problems of slag formation, less slag for dephosphorization were solved by adding manganese ore and earlier slag.
