【Abstract】 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 ℃.更多还原
