摘　　要：西昌钢钒新建铁水脱硫项目采用喷射冶金技术对铁水进行脱硫,通过载流气体将镁基、钙基脱硫剂喷射入高温熔融铁水。对载气流量以及钙基、镁基脱硫剂在铁水中的滞留时间进行分析,分析表明应尽量减小脱硫粉剂的粒径,延长脱硫粉剂在铁水中的滞留时间。生产实践表明,采用增加喷枪插入深度的方法有助于提高脱硫效率。The new desulfurization project of Xichang Steel&Vanadium adopts jet metal⁃lurgy technology to desulfurize hot metal,through the carrier gas will be magnesium,calcium-based desulfurizer jet into the high-temperature hot metal.The carrier gas flow rate and the retention time of calcium-based and magnesium-based desulfurizer in hot metal are analyzed,and the analysis shows that the particle size of the desulfurization powder should be reduced as much as possible to prolong the retention time of the desulfurization powder in hot metal.Production practice shows that the method of increasing the insertion depth of the lance helps to improve the efficiency of desulfurization.
