1573KにおけるCaO-SiO_2-FeO_x系状態図液相線に及ぼすAl_2O_3とMgO添加の影響 Effect of Al_2O_3 and MgO Additions on Liquidus for the CaO-SiO_2-FeO_x System at 1573K
Phase diagrams for the CaO-SiO<SUB>2</SUB>-FeO<SUB>x</SUB>-Al<SUB>2</SUB>O<SUB>3</SUB> or-MgO systems at various oxygen partial pressures are necessary for the design of raw material for ironmaking, the analysis of smelting reaction and sintering process. To clarify the effect of Al<SUB>2</SUB>O<SUB>3</SUB> or MgO content on the formation of melts in the sintering process is important for the development of new sinter. In this study, liquidus for the CaO-SiO<SUB>2</SUB>-FeO<SUB>x</SUB>-Al<SUB>2</SUB>O<SUB>3</SUB> or -MgO systems at various oxygen partial pressures were observed at 1573K by using chemical equilibration technique. The liquid phase area changed with adding Al<SUB>2</SUB>O<SUB>3</SUB> or MgO. The effect of the Fe<SUP>3+</SUP>/Fe<SUP>2+</SUP> ratio on the melting mechanism is discussed.
