摘　　要：结合莱钢J55、L360等低硫钢冶炼的生产实践,分析了"铁水预脱硫处理—转炉—LF钢包精炼—连铸"全流程各工艺环节的硫含量控制技术,指出铁水预脱硫处理、转炉冶炼、LF精炼过程硫含量控制技术是低硫钢冶炼的关键技术环节。通过采用全流程硫含量控制技术,生产出了硫的质量分数最低为0.002%的低硫钢。Based on the smelting practice of low-sulfur steel,such as J55,L360,the sulfur control technology during the process of ＂hot metal predesulfurization-converter-LF refining-continuous casting＂ was analyzed.The key processes of sulfur control are hot metal predesulfurization,converter and LF refining.By using the sulfur control technology during the whole process,the low-sulfur content steel is produced.The lowest sulfur content is 0.002%.
