摘要
通过 Ca O- Ba O- Ca F2 渣系和锰铁熔体间的平衡分配实验 ,研究了 Ba O、Ca F2 、温度及锰铁熔体中碳、锰含量对磷平衡分配比的影响 ,并计算了 Ca O- Ba O- Ca F2 渣系的磷酸盐容量及 P2 O5 的活度系数。 135 0℃时 ,该渣系的磷酸盐容量为 3.2× 10 2 4～ 2 .0× 10 2 5 ,渣中 P2 O5 的活度系数在 10 - 2
The experiments on Mn and P distribution between CaO BaO CaF 2 slags and ferromanganese melts were carried out. The effects of temperature, BaO, CaF 2, original C and Mn content in hot metal on P distribution were investigated according to the experimental results. The phosphate capacity (3.2×10 24 ～2.0×10 25 ) and the activity coefficient of P 2O 5 in slags (10 -25 ) were evaluated at 1 350 ℃.
