摘要
对超低硫钢生产过程中LF精炼渣脱硫进行了理论分析与工业试验,结果表明:优化精炼渣成分,提高光学碱度,强化钢水及炉渣脱氧,选择合适的渣量是提高脱硫效率的有效手段;武钢管线钢生产中LF平均脱硫率为55%;CaO-SiO2-Al2O3-MgO(5%)渣系等硫分配比曲线图可指导生产选择合适的炉渣成分。
The theoretical analysis and commercial experiment of desulfuration of ladle furnace for the refining of ultra - low sulfur steels are carried out in this paper, the results are： optimizing the composition of slag, increasing the optical basicity, deeply deoxidizing of both molten steel and slag; determining the proper slag weight are the effective methods of increasing the sulfur removal percentage, the average sulfur removal percentage of LF process in WuHan steel is 55%; the Iso - sulfur partial ratio charts in slag system of CaO - SiO2 - Al2jO3 - MgO（5%） can instruct workers to determine the proper composition of slag.
