摘　　要：分析了某厂 30 0t转炉使用低硫铁水冶炼时熔池硫含量的变化规律及影响因素。结果表明 :废钢的熔化是熔池硫含量升高的主要原因。钢渣间的脱硫反应主要发生在吹炼的后期。降低废钢比 。The changes on sulfur content in bath during melting in 300?t converter with low sulfur hot metal and the factors in fluencing them are analyzed in this paper. The results show that steel scrap melting is the main reason for increase in sulfur content in bath. The desulphurization reaction between slag often occurs in the final stage of blowing. Low scrap ratio, high basicity ratio of slag at blowing end and low FeO content in slag can help to obtain low final sulfur content in bath.
