摘要: 针对高硫硅锰合金,采用高温硅钼炉、XRD以及常规化学分析法,研究了CaO-BaO-MgO-SiO2-CaF2五元脱硫渣系中MgO,CaO,BaO对脱硫效果的影响.研究结果表明:随着BaO与CaO质量比的增加,脱硫率先升高后降低.当MgO的质量分数为8%,CaF2的质量分数为10%,BaO与CaO的质量比为09143时,脱硫率达到944%;当MgO的质量分数为12%,CaF2的质量分数为14%,BaO与CaO的质量比为07879时,脱硫率达到954%.当CaO的质量分数为35%,BaO的质量分数为32%时,随着MgO质量分数的增加脱硫率先升高后降低,MgO的质量分数为8%时,渣的脱硫能力最高.

Abstract: The effects of MgO, CaO, BaO in CaOBaOMgOSiO2CaF2 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 CaF2 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 CaF2 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 %.
