在1573-1673K时测定了锰在BaO-BaF_2和Mno渣和Mn(62-73%)-Fe-C饱和熔体之间的平衡分配比.研究了渣的成分、氧分压和温度对标分配比的影响,发现锰的平衡分配比是随着氧分压和渣中BaO含量的增加而增加.在氧分压较高时.向BaO-MnO渣中附加BaF2,为减少镜的损失和使锰铁脱磷能够进行提供了有利条件.在氧分压一定时,在渣与碳饱和的镜铁平衡时,BaO与MnO的摩尔分数比是随着渣中BaO的增加而减少的.温度高导致锰的分配比低.对于BaO(50%)-BaF2(47%)-MnO(3%)渣;温度对锰容量的影响可以表示为:Nn(1)十1/202=(MnO)这个反应热,在研究的温度一定时计算为一定时计算为-415kJ/mOl
The equilibrium distribution of manganese between BaO-BaF 2 and Mno slag and Mn (62-73%) - Fe-C saturated melt was determined at 1573-1673K. The effects of slag composition, partial pressure of oxygen and temperature on the standard partition ratio were studied. It was found that the equilibrium distribution ratio of manganese increased with the partial pressure of oxygen and the content of BaO in the slag. When the oxygen partial pressure is high. Addition of BaF2 to BaO-MnO slag provides favorable conditions for reducing the loss of the mirror and enabling dephosphorization of ferromanganese. When the oxygen partial pressure is constant, the mole fraction of BaO and MnO decreases with the increase of BaO in the slag when the slag and carbon-saturated mirror iron are in equilibrium. High temperature leads to low manganese distribution. The effect of temperature on the manganese capacity can be expressed as: BaO (50%) - BaF2 (47%) - MnO (3%) slag The reaction heat can be expressed as: Calculated as a certain amount of time is calculated as -415kJ / mOl
