Fe_tO-MnO-MO_x (MO_x=PO_2.5, SiO₂, AlO_1.5, MgO, CaO)系スラグ-溶鉄間のマンガン平衡に関する考察

抄録

The previous results on manganese distribution between liquid iron and Fe_tO-containing slags have been summarized. The apparent equilibrium constant K'_Mn=N_MnO/([%Mn]·N_FetO) in the Fe_tO-MnO slags can be expressed as log K'_Mn=7572/T-3.559
The variations of K'_Mn with slag compositions in the Fe_tO-MnO-MO_X(MO_X=PO_2.5, SiO₂, AlO_1.5, MgO, CaO) ternary melts as well as in MgO-saturated CaO-Fe_tO-SiO₂-MnO slags have been discussed on the basis of the regular solution model and the RICHARDSON's ideal silicate mixing.
