| Abstract: | In this paper, retained strength of coated sand baked in the variant temperature were measured, fractures of all samples by application of SEM observation were analyzed, the heat bending curve of coated sand was measured. Based on the results, the feature of high-temperature coated sand and collapse coated sand was compared. Effects of heat performance on strength?fractures and bending of coat sand were analyzed. |
