摘　　要：介绍了承钢150 t铁水脱硫工艺概况,生产初期存在脱硫效率低、回硫严重等问题,不能满足大板坯以优质钢种为主的生产需求。通过在喷吹过程中顶加石灰、优化扒渣操作、改善脱硫反应的动力学条件等措施,改善了铁水包内铁水的搅拌效果,顶加的石灰将脱硫产物固定在顶渣中且稠化了脱硫终渣,扒渣效果得到有效改善,提高了钝化镁粒的有效利用率,有效防止了铁水回硫。镁粒的脱硫效率提高了24.2%,回硫率降低了32.2%。The present paper introduces the technique of desulphurization process in 150 t ladle. According to the cur- rent status of hot metal desulphurization production at ehengde Iron and Steel company. Some relative factors have been an- alyzed comprehensively and systematically, some proper countermeasure has been suggested. Production results show that under the current processing conditions very satisfactory results of desulphurization have been achieved
