摘　　要：以水钢高V高Ti铁水为研究对象,通过对铁水复合脱硫工艺热力学计算,及脱硫动力学条件的优化,共同研究复合脱硫剂成分的优化配比,获取适宜的,得出最佳复合脱硫工艺,达到提高铁水脱硫效率,优化水钢高炉炉料结构,降低生产成本的目的。研究表明:Ca O和Ca O/Ca F_2对Mg基脱硫剂的优化配料及强化脱硫的动力学条件对镁基脱硫剂脱硫深度和脱硫率有明显的提升,实验最佳脱硫率达到66.5%。Taking ShougangShuicheng Iron ＆ steel （Group） Co. Ltd＇ s high-V-high-Ti liquid steel as the research object, this paper adopts thermodynamic calculation to calculate liquid steel＇ s compound desulfurization process and optimizes the condition of kinetics of desulfurization, with the aim to search for the optimized compositon- propotion of compound desulfurizer, find out the optimized compound desulfurization technology, improve desulfuriza- tion efficiency, optimize the burden structure, and reduce the production cost. The conclusions have been drawn that CaO and CaO/CaF2 can significantly optimize the composition proportion of Mg base desulfurizer, and the strength- ened dynamic conditions for chemical reactions can greatly improve the desulfurization intensity and efficiency for Mg base desulfurizer. In additon, the best desulfurization rate reached 66.5% during the experiment.
