INVESTIGATION ON SLAG-REFRACTORY INTERACTION IN LADLE USING COMPUTATIONAL TECHNIQUES

Abstract: Thermodynamic computational packages MTDATA and FactSage have been used to carry out calculations on the variation with temperature of the phases precipitated on cooling in both oxidising and reducing conditions of a typical ladle slag composition, in the temperature range 1700 - 900°C. The current coverage of the databases associated with the computational packages is discussed in relation to their application to slag - refractory interaction and the validity of the results is compared with some relevant experimental data and phase equilibrium studies
