Abstract

PURPOSE: To improve the high temprature compressive strength of the self-curing mold by penetrating the liquid comprising dispersing material which changes mineral composition partly to liquid phase in a high temperature region and material which stabilizes this liquid phase to solid phase at high temperature in the surface layer of the self-curing mold then drying the same.
CONSTITUTION: Kaolinite is used as material which changes mineral composition partly to liquid phase at a high temperature region (400W1600°C) and alumina is used as material which stabilizes this liquid phase to oxide at high temperature in accordance with the formula. Water or alcohol which does not react with these materials is used as a medium for dispersing these materials. The self-curing mold which has been compression-cured by adding organic binders is dipped for about 5 minutes in the foregoing dispersion medium and is dried for 5 hours. This casting mold is heated up to near 1200°C when poured with molten steel and therefore bonding force is imparted among the sand particles through reaction between kaolinite and alumina by the formula, thus the good high temperature compressive strength is provided to the surface layer part.
