  • Defective engine block recycling method in continuous casting line
    Patent number: 9732397
    Abstract: A defective engine block recycling method in a continuous casting line includes inserting a bore pin into an engine block mold, fitting a real liner to an outer circumferential surface of the bore pin, and injecting molten aluminum into the engine block mold to cast an engine block body. If an abnormality is generated in the engine block mold or the molten aluminum and if a defect is expected to generate in the engine block body, a defective engine block unit is produced by fitting a dummy liner, which is made of a material identical with or similar to a material of the engine block body, to the bore pin. The defective engine block unit thus produced is directly melted and recycled.
