摘　　要：压壳的金属型顶浇工艺最主要的是解决落差冲击造成的乱流卷渣问题,以及指向性凝固问题。本文从浇铸落差与浇口大小对压壳渣孔的影响进行了计算分析,借助模流分析软件Anycasting对下模底部不同高度冷却柱的铝液充型进行了模拟,并且将模拟与计算分析结果与生产实践验证。结果表明,解决与改善了常见的渣孔问题。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.
