The thermomechanical properties of foundry sand are analyzed. The thermal and dynamic action of the melt on the mold wall during the casting and solidification of metal is considered, along with its role in the formation of surface defects. The influence of the heating time on the deformation of common types of foundry sand is determined by simulating industrial ingot casting. The deformability of the foundry sand is related to the defects that form on the ingots and the pliability of the sand. Measures are proposed to prevent surface defects. Scabs, gaps, and hot buildup on castings may be attributed to deformational changes and disintegration in the surface layers of the foundry sand. In terms of surface-defect prevention and environmental protection, sodium-silicate foundry sand and phosphate sands are the best.
