通过ＢａＯ－卤化物渣系和锰铁合金之间磷的分配平衡实验，测定了实验渣系的磷酸盐容量。结果表明，脱磷剂中不同卤化物的加入对增大渣系脱磷能力的影响程度不同，按大小顺序为ＢａＦ２＞ＢａＣｌ２＞ＣａＦ２＞ＣａＣｌ２，实验得到ＣａＯ替代ＢａＯ，ＭｎＯ２替代ＢａＦ２时对渣系脱磷能力的影响关系。在此基础上，用ＢａＯ－ＢａＦ２系熔剂对锰铁合金进行氧化脱磷工艺性实验，实验发现，采用５６％ＢａＯ－２４％ＢａＦ２－１０％Ｆｅ２Ｏ３－１０％ＭｎＯ２熔剂，熔剂添加量为１０ｇ／１００ｇ合金，温度１５７３Ｋ，脱磷率达到６２％，温度升高到１６７３Ｋ，脱磷率降低到３０％。
Through the balance experiment of phosphorus balance between BaO-halide slag system and ferromanganese alloy, the phosphate capacity of experimental slag system was determined. The results show that the addition of different halides in dephosphorizer has different effects on increasing the dephosphorization capacity of slag system. BaF2> BaCl2> CaF2> CaCl2 in order of size, CaO instead of BaO and MnO2 instead of BaF2. Dephosphorization ability of the relationship. On this basis, BaO-BaF2 flux was used to oxidize dephosphorization of ferromanganese alloy. The experimental results showed that the flux of 56% BaO-24% BaF2-10% Fe2O3-10% MnO2 flux was 10g / 100g Alloy, temperature 1573K, dephosphorization rate of 62%, the temperature increased to 1673K, dephosphorization rate decreased to 30%.
