摘要
The effects of MgO, CaO, BaO in CaO-BaO-MgO-SiO2-CaF2 slag on the desulfurization of SiMn alloy with high sulfur were studied in a silicon molybdenum furnace, and with XRD and chemical analyses. The results showed that the desulfurization ability rises first and then falls with increasing m (BaO) ∶ m (CaO) ratio. When the mass fractions of MgO and CaF2 are 8% and 10% respectively, and m (BaO):m (CaO) is 0.914 3, the desulfurization efficiency reaches to 94.4%. When the mass fractions of MgO and CaF2 are 12% and 14% respectively, and m (BaO):m (CaO) is 0.787 9, the desulfurization efficiency reaches to 95.4%. Meanwhile, when the mass fractions of CaO and BaO are 35% and 32% separately, the desulfurization ability rises first and then falls with increasing the mass fraction of MgO, and the desulfurization effect is the best when the mass fraction of MgO is 8%.
