摘要
用静态平衡法研究了含有 Ｂ２Ｏ３的 ＭｇＯ－ＣａＯ－ＳｉＯ２－Ｂ２Ｏ３－Ａｌ２Ｏ３五元渣系的脱硫率与炉渣组成变化的关系．当三元碱度Ｒ３小于２．２时，脱硫率随Ｒ３增大而增大，随Ｂ２Ｏ２含量的增加而减小； Ｒ３较大时，其增大对脱硫率影响不大，这时 Ｂ２Ｏ３含量的增加有利于改善动力学因素，提高脱硫率．
Boron-rich slag system is studied to acquire the relationship between desulfuration ratio and slag composition. When the ternary-basicity is lower than 2.2, accretion of it improves desulfuration largely and the improvement is smaller when it is high. Accretion of B_2O_3 reduces the desulfuration ratio when the ternary-basicity is low, but it increases the fluidity of the slag, which improves desulfuration as the basicity is high.
