摘　　要：杭钢转炉炼钢厂因转炉的炉熔比0.74-0.8m^3/t,及前期炉渣平均（FeO）≥20%,铁水的（Si＋P）含量较高等原因,在开吹4-5min时易发生炉渣喷溅。在分析前期产生炉渣喷溅几个特征的基础上,提出了降低喷溅的对策。Slag splashing tended to happen at 4~5 min after blowing start at the converters of Hangzhou Steel due to a V/T of 0.74~0.80m3/t,early-stage average slag（FeO）≥20% and high Si＋P contents in hot metal.Countermeasures for reducing splashing are proposed based on analysis of the splashing characteristics.
