Casting Process Design and Numerical Simulation on Thin-Walled Spherical Shell
The structure,technical requirements and original process of the spherical shell were introduced,and the causes of shrinkage defects on the side wall were analyzed.Aiming at the problem,the parting and gating system were optimized,and the venting system was adjusted after checking.The process optimization scheme and casting quality were predicted and analyzed by ProCAST software,and reasonable gating and feeding system were determined.After production verification,the first-pass rate of castings was increased from 54.5%to 89%.
