在硅化钼炉和１００ｋｇ级中频感应炉中，采用ＢａＣＯ３基熔剂对高炉锰铁进行了脱硅脱磷联动实验。实验结果表明：对硅含量（质量分数）小于等于１．０％的高炉锰铁经一次预脱硅后再进行氧化脱磷时，可获得约９０％的脱硅率和４０％～６２％的脱磷率，在控制实验体系氧位下，联动处理全过程的锰氧化损失Δ［Ｍｎ］＜１．０％。锰铁合金脱磷前的硅含量显著影响脱磷率，将硅含量控制在小于等于０．２８％时，可得到的相应脱磷率大于４０％。ＢａＣＯ３基熔剂作为联动处理时的脱硅和脱磷剂，其优化组成为ＢａＣＯ３（８０％）－ＢａＦ２（１０％）－ＭｎＣＯ３（１０％）。
In the molybdenum silicide furnace and 100kg intermediate frequency induction furnace, BaCO3-based flux was used to study the desiliconization and dephosphorization of blast furnace ferromanganese. The experimental results show that about 90% desilication rate and 40% -62% of the desilication rate can be obtained for the blast furnace ferromanganese with a silicon content (mass fraction) less than or equal to 1.0% after pre-desilication followed by oxidative dephosphorization Dephosphorization rate, in the control experimental system oxygen level, the whole process of linkage oxidation of manganese oxidation loss [Mn] <1.0%. The silicon content before dephosphorization of ferromanganese alloy significantly affects the dephosphorization rate. When the silicon content is controlled at 0.28% or less, the corresponding dephosphorization rate of more than 40% can be obtained. As the desilication and dephosphorization agent, the optimized composition of BaCO3 flux is BaCO3 (80%) - BaF2 (10%) - MnCO3 (10%).
