Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to an air duct for investment casting. Background Art

[0002] Investment casting is a traditional casting process. The quality of the investment casting shell directly affects the quality of the casting. The drying process in the shell preparation process is crucial. The drying of the shell is affected by the temperature and humidity of the environment. Too high temperature and too low humidity will cause the shell to dry too quickly and shrink over a large area, and cracks, peeling and falling off will occur at the edges and corners; too low temperature and too high humidity will cause the drying speed to be too slow, and the shell that is not completely dried will partially dissolve during the application of the next layer. Poor quality of the shell will eventually lead to defects such as inclusions, shrinkage holes, and pores in the casting, causing the casting to be scrapped. Utility Model Content
