Casting process based on cylinder sleeve in ship equipment

The invention belongs to the field of ship equipment, and discloses a casting process based on a cylinder sleeve in ship equipment, which comprises the following steps of: 1, pouring an outer mold according to a cylinder sleeve mold; secondly, burrs of the casting are polished through polishing equipment; thirdly, dye is sprayed to the surface of the formed casting, and preheating is conducted; fourthly, after the casting is cooled, the casting is taken out of the mold, and the top end of the cylinder sleeve is punched; and fifthly, the cylinder sleeve is packaged and transported. According to the polishing equipment, by arranging the outer polishing mechanism and the rotating mechanism, the surface of the cylinder sleeve can be polished without dead corners, burrs on the surface of the cylinder sleeve are effectively removed, the smoothness of the surface of the cylinder sleeve is improved, dye smearing is facilitated, and the product quality of the cylinder sleeve is improved. 本发明公开了船舶设备领域的，一种基于船舶设备中缸套的铸造工艺
