    Summary:The compo-casting of ceramics by cast iron is expected to be one of the useful casting process that can expand the application fields of cast iron. The largest problem in compo-casting method is cracking Caused by thermal shock. Although this cracking can be prevented by reducing the thermal stress by preheating ceramics. the necessary preheating temperature is high and its precise control is difficult at practical foundries. In this study, we tried to estimate numerically the critical preheating temperature of ceramics using the thermal stress analysis during transient thermal conduction and the Newman's diagram. We also found that the preheating of ceramics to reduce thermal stress can be replaced with placing an appropriate cast iron covers around the ceramics. We describe new compo-casting method that needs no preheating of ceramics and proved the usefulness experimentally.
