摘　　要：针对CaO-CaF2系脱硫剂对RH浸渍管侵蚀严重、污染环境缺点,开发出一种以CaO-Al2O3-SiO2渣系为主,添加部分高碱度、高硫容组分的预熔型脱硫剂。现场试用结果表明:脱硫剂具有脱硫速度快、对真空槽侵蚀轻、脱硫率高的特点,平均脱硫率达到50%以上。In light of the disadvantages of desulphurizer of CaO-CaF2 system such as severe erosion to the RH immersion tube and heavy contamination of the environment, a new CaO-Al2O3-SiO2 system based pre-melted desulphurizer was developed by adding some components with high basicity and good sulfur capacity. The results obtained from the experiments shows that the new pre-melted desulphurizer is characterized with rapid desulphurization rate, less erosion to the RH refractory and good desulfurization efficiency. The average desulfurization rate is over 50%.
