Optimization of Valve Body Process based on HZCAE
To solve the shrinkage defects that exist in valve body steel castings produced by a company, based on HZCAE simulation results and combined approach, the process for the castings was optimized. After several simulation tests, the final solution is the pouring temperature of 1 600 ℃, adding the riser on the flange. The simulation results with the optimized gating system show that the shrinkages on the flange were basically eliminated. The actual production using process optimization shows the location of the shrinkage is the same as CAE simulation results, using the ultrasound technology to detect the actual casting. So HZCAE software can solve the shrinkage problems in the castings and improve the quality of the castings.
