Abstract：Based on the analysis of the casting process difficulties of large thin-wall impeller,the casting process was optimized by using 3D software and simulation software,and the casting process of dual-phase stainless steel impeller was numerically simulated.The results show that by analyzing the location and type of casting defects,optimizing the casting process and carrying out numerical simulation calculation,virtual trial casting can effectively improve the hot spot state,achieve the purpose of eliminating and controlling the defects,and make the casting meet the quality requirements.
