摘　　要：结合高速轨钢生产实践,分析了“铁水预处理—转炉—LF精炼—RH精炼—连铸”流程各工艺环节下钢水中硫含量及控硫技术,明确了LF精炼是决定产品硫含量的关键环节,通过各环节协同控制生产的高速轨钢中硫的质量分数最低可达0.002%。Combined with the production practice of high-speed rail steel,the sulfur content in molten steel and its control technology in the whole process of"hot metal pretreatment-converter-LF refining-RH refining-continuous casting"are analyzed,and it is clear that LF refining is the key link to determine the sulfur content of the product,and the sulfur content in high-speed rail steel produced by coordinated control of all links can reach 0.002%at the lowest.
