Abstract

Metal to be cast is melted in melting chamber of casting furnace. Molten metal flows through a nozzle of the melting chamber is atomized by a stream of heated compressed air. Droplets of molten metal are carried by the air stream to a mold onto which the metal is cast to form a thin even molding. The hot air stream prevents the molten metal droplets from solidifying until they reach the mold. The amount of metal cast and the thickness of the molding may be controlled by adjusting the velocity of the air stream and the distance from the nozzle to the mold.
