Optimization of investment casting process of ZL114A alloy seal sleeve
The investment casting process of ZL114A alloy seal was simulated numerically by Procast software,and the loose defects were found in the flange and the thin-walled area of the casting,and the accuracy of the numerical simulation results was proved by the process test.The causes of defects were analyzed,and on the basis of the first version of the casting process,air-cooling measures were taken to achieve the purpose of rapid solidification of castings.Numerical simulation and actual production results show that the casting defects are completely eliminated and can meet the requirements of use.
