Abstract

Based on the minimum Gibbs free energy method, a modified thermodynamic model was established to predict the composition of inclusions during the calcium treatment process. Three types of phase were contained in the steel-inclusion system, including the molten steel phase, the liquid inclusions phase, and the solid inclusions phase. The Wanger model was applied to calculated activities of elements in the molten steel. Reported interaction parameters were evaluated and used to improve the accuracy of thermodynamic calculation results. The coexistence theory was applied to calculate activities of Al2O3 and CaO in liquid inclusions. According to the thermodynamic calculations, the effect of T.Ca content in the molten steel on the transformation of inclusions was discussed. Combining the established thermodynamic model and a calcium yield prediction model, a software for precise control of calcium treatment process was also developed.
