摘　　要：针对高级别管线钢的钢水生产流程,硫含量变化及控制生产试验沿"LD→BAr→LF→RH→CC"生产工艺流程进行.试验结果表明,转炉氧化性气氛使得转炉过程脱硫能力有限;转炉出钢、吹Ar和LF过程有良好的脱硫反应条件,脱硫效果好;添加料带入的硫导致RH过程钢水中的硫略微上升;钢渣脱硫反应使得中包过程钢水中的硫得到些微去除.The change and control of sulfur content in molten high-grade pipeline steel is tested through the production process of ＂LD- BAr-LF-RH-CC＂. The results show that the desulfurization ability of converter process is limited because of its oxidizing atmosphere. The processes of steel-discharging, BAr and LF are good for desulfurization. Sulfur in the added materials causes sulfur in molten steel to rise slightly in RH process. Desulfurization reaction in steel-slag makes sulfur of molten steel slightly removed in the tundish process.
