摘　　要：针对一炼钢厂转炉→精炼（LF＋RH）→连铸工序,转炉在生产超低磷钢中常用双渣、双联法生产,常规产品采用单渣法生产。通过转炉工艺优化调整,采用单渣法也可满足超低磷品种脱磷要求,逐步实现了单渣法连续生产超低磷品种钢,脱磷率稳定≥96%,降低了转炉生产成本,简化了生产组织流程。At No. 1 Steel-making Plant,the production process ： converter→ refining（ LF ＋ RH） →continuous casting is to produce ultra-low phosphorus steel with single slag process instead of duplex process and double slag process,continuous production with 6 converters as a group,dephosphorization rate ≥96. 75%,which has made production stable and reduced production costs. Currently single slag process can meet the demand of dephosphorization of ultra-low phosphorus steel.
