Development of Calculation Program for Thermophysical Properties of Artificial Sand Mold

The heat transfer of the mold during the casting process has been calculated by considering the mold as a uniform isotropic material. Since the mold was not a uniform isotropic material, the calculation was performed with approximate values, and in particular, estimated values were used when considering compaction and binder addition amount. In this study, calculation of the thermal properties of the sand mold was developed. An algorithm for calculating thermal conductivity and specific heat based on a thermal resistance model in the case of mono-dispersed was developed and applied to sand molds with various size distributions. The thermal properties of sand were calculated for artificial sand, and relatively close values were obtained compared to the experimental values.
