Abstract

PURPOSE: To improve the quality of a product by casting an outside layer then casting a small amt. of a molten metal having a low m.p. during the solidification or partial solidification of the inside surface of the outside layer to mix and solidify the same with the cast outside layer and casting an inside layer.
CONSTITUTION: After the outside layer A is cast, the molten metal B having the low m.p. is mixed at the small amt. corresponding to the pouring thickness of 1W5% of the barrel diameter of the product during the solidification or partial solidification of the outside layer A to mix the molten metal with part of the outside layer. The inside layer C is cast after the inside surface of the mixed layer solidifies. The outside layer and inside layer are thoroughly metallurgically adhered by the above-mentioned method, by which the product having the extremely high quality is obtd.
