Abstract：The most important part of the metal mold top gravity casting process of the shell was to solve the problems of turbulent flow and slag entrainment caused by drop impact and directional solidification.The influence of casting drop and gate size on shell slag hole was calculated and analyzed.The liquid aluminum filling patterns of cooling columns at different heights at the bottom of the lower mold were simulated with the help of mold flow analysis software Anycasting,and the simulation,calculation and analysis results were verified with the production practice.The results show that the common slag hole problem is solved and improved.
