摘要	Casting failures are caused by the thermal stress and hydraulic pressure of the molten metal during the investment casting process due to the insufficient high-temperature strength of the ceramic shell. This work investigated how the high-temperature flexural strength of aluminosilicate ceramic shells varies with temperature, different types of back-up sands, manufacturing processes, and the thickness of back-up coats by a three-point bending test. The results showed that flexural strength at room temperature is half of the high-temperature flexural strength at 1000 & DEG;C, almost equal to that at 1200 & DEG;C, and about three to eight times higher than that at 1400 & DEG;C. In comparison with the fused silica, aluminosilicate shells have inadequate high-temperature flexural strength at 1400 & DEG;C, regardless of mullite and bauxite as back-up sands. In addition, the mullite shell prepared by the automated robotic arm has higher flexural strength than one made through the manual operation process. Finally, the high-temperature flexural strength of the bauxite shell is unaffected by the increasing thickness of back-up coats. This study provides a guide to improve the high-temperature flexural strength of aluminosilicate shells and a theoretical foundation for reducing defects in castings.
