Casting Process Design and Optimization of Aluminum Alloy Intermediate Casing
The difficulties of casting and forming process were analyzed according to the structural characteristics and metallurgical quality requirements of aluminum alloy intermediate casing castings.Through the design of bottom-injection investment casting system,stainless steel tube insert casting and ceramic core are adopted to solve the problem of elongated hole difficult to form,and the improvement measures such as vibration casting and local wind cooling are implemented.At the same time,the casting process was further optimized based on the problems in the trial production of castings.According to the improved test results,the optimized casting process scheme of the intermediate casing was reasonable and feasible.
