Casting process optimization for the impellor of 200ZJA slurry pump

A design method of gating system and riser for high chromium cast iron casting was introduced in this paper. The casting processes of the impellor of 200ZJA slurry pump were simulated using ProCAST software. The simulation results were consistent with the practical production test. The mold-filling and solidification stages of the casting were numerically analyzed. The original casting process was improved according to the simulation results and the practical production test. By modifying the original process, the shrinkages at the joint between axle head and the main body of the impellor were eliminated, and the casting with good quality was obtained.
