Influence of mold flux on the thermal processes in the mold

Abstract

Analysis of the literature on the thermophysical properties of mold flux shows that the measurement results for the thermophysical properties of the slag vary significantly, depending on the method employed. On that basis, a model is proposed for calculating the heat flux in the system consisting of the ingot, the slag film, and the mold. Literature data regarding the properties of the slag and industrial data regarding the mold’s wall temperature are employed here. The proposed model permits investigation of the heat flux as a function of the thickness and physicochemical properties of the mold flux.
