説明
As a fundamental study of physical chemistry of steelmaking slags, equilibria between hydrogen-water gas mixture and liquid slags contained in solid iron crucibles have been measured for four binary slags of FetO-CaO, FetO-SiO2, FetO-TiO2 and FetO-Al2O3 systems at 1400 °C. From the data, the activity of iron oxide and the ratio of ferrous and ferric iron (Λ = Fe3+/Fe2+) were calculated for the composition of slags. In view of ionic theory, a regular solution model for cations was applied to evaluate the thermodynamic properties of complex slags from those of the binary slags. Three binary slags of FetO-SiO2, FetO-CaO and FetO-TiO2 systems conformed to the regular solution model within the experimental error except for the extremely FeO rich region. It was confirmed that the oxygen distribution between slag and metal was quantitatively expressed with this model over the wide range of slag composition.
