摘要

Thermodynamics of the MnO-SiO_2-TiO_2 and the MnO-SiO_2-TiO_2 systems have been studied for optimizing the property of oxides in steel. Iso-activity curves for the determination of the composition of steel equilibrated with such oxides, have been estimated in the wide range of liquid phases. Although in the study of the MnO-SiO_2-TiO_2 system, iso-activity curves of SiO_2 and TiO_2 were partially obtained due to the lack of integration limit on the saturated line of SiO_2 and TiO_2, integration limits of each component have been derived by ternary Gibbs-Duhem equation. This enabled the estimation of steel composition in equilibrium with a wide range of the oxide system. In addition, the behavior of sulfur in the MnO-SiO_2-TiO_2 an the MnO-SiO_2-TiO_2 oxides in steels were simulated using the sulfide capacities of these systems in order to optimize processing conditions.
