Oxidizing Capability of Refining Slags Containing BaO

摘要: According to the coexistence theory of slag structure melts, the oxidizing capability of the refining slag CaO-MgO-FeO-Al2O3-SiO2 is studied and the relationship between the mass action concentration of FeO (NFeO) and the activity of FetO (αFetO) for this slag is found to be as NFeo=0.656 1 αFetO. Furthermore, the calculating model of oxidizing capability of the refining slag BaO-CaO-MgO-FeOAl2O3-SiO2 is established. A satisfactory result is obtained when using the above oxidizing capability relationship to calculate the desulphurizing capability of such refining BaO-slags.
