Abstract

PURPOSE: To obtain casting mold surface of small occurrence ratio of troubles such as sand burning, by spraying Al powder simultaneously with a mixed soln. made by addition with a prescribed ratios of heat resistant oxides, carbon, and silicon carbide to a soln. of caustic alkali.
CONSTITUTION: To an aqueous soln. such as aqueous 5W20% NaOH or KOH soln. are added 0W100wt%, based on said soln., heat resistant oxide i.e. single substance or compound of Al2O3, MgO, SiO2, ZrO, TiO2 etc., carbon, and carbide such as silicon carbide, Said aqueous soln. and powder or fine powder of Al are simultaneously painted by spraying to the surface of a casting mold to form heat resistant solidified coating. The ratio of alkali quantity to pure Al powder is 1:(0.6W1.0). Hereby the surface treatment of the casting mold is industrially performed simply, easily, and economically with elimination of the heat treatment process to be conducted after painting of facing material to the mold surface unlike in conventional process.
