Embodiment Construction

[0054] Now, will refer to Figure 5 with Image 6 A preferred embodiment of the method for recycling defective engine cylinders in a continuous casting production line according to the present invention is described.

[0055] For the sake of convenience, the case of manufacturing an engine block unit including an aluminum engine block main body 10 and a cast iron bushing 20 by a die casting method will be described.

[0056] Since the die casting method is described in the background art, it will not be described repeatedly. The following description will focus on the features of the present invention.

[0057] A method for recovering a defective engine cylinder block in a continuous casting production line according to the present invention includes: inserting a hole pin 40 into an engine block mold M; assembling a real bush 20 on the outer peripheral surface of the hole pin 40; and melting aluminum It is injected into the engine block mold M to cast the engine block main body 10....

Abstract

A defective engine block recycling method in a continuous casting line is provided and 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 produced is directly melted and recycled.

Description

Technical field [0001] The invention relates to a method for recovering defective engine cylinders in a continuous casting production line. More particularly, the present invention relates to a method for recovering defective engine blocks in a continuous casting production line, in which the method is expected to be produced during continuous casting of engine blocks used in motor vehicles, ships, airplanes, etc. For defects, use aluminum dummy bushings instead of cast iron bushings to cast the engine block. The defective engine block produced in this way was immediately recycled into the aluminum ingot. This eliminates the need to remove cast iron bushings from the aluminum engine block, thereby reducing costs and improving the quality of recycled aluminum ingots. Background technique [0002] In recent years, engine blocks for motor vehicles, ships, airplanes, etc. are often made of lightweight aluminum instead of cast iron. Compared with the cast iron engine block, the alu...
