Abstract
PURPOSE: To quickly cool and solidify the teemed molten metal and produce a casting having dense internal structure by beforehand bringing a mold into contact with an inert refrigerant of nonoxidative type.
CONSTITUTION: A sprue 3 provided with a pouring cup 4 is provided to a mold material 1 reinforced with a molding flask 2, and this sprue 3 is communicated with a mold cavity part 6 by way of a runner 5. Evaporated gaseous CO2 or N2 is introduced into the cavity part 6 through a cold gas lead-in pipe 8 opening in the cup 4, to cool the same and to expell the O2 existing in the void parts among the sand particles of the internal structure thereof, thereby forming a nonoxidative atmosphere. It is preferable to carry out the introduction of this cold gas in large excess until the inside surface of the material 1 attains temps. below room temp. Thereby, the teemed molten metal is rapidly cooled, and the cast product of dense internal structure and superior mechanical characteristics is obtained.
