利用FLOW-3D软件，对某本体铸件生产过程中出现的缩孔及疏松缺陷进行了模拟。模拟结果显示，在缺陷一侧增加浇口，同时对各浇冒口横截面及距离进行相应调整，缩孔及疏松缺陷消除。验证结果表明，根据模拟结果对石膏型低压铸造工艺进行优化后，试制的某本体铸件未见缩孔及疏松等铸造缺陷。
The shrinkage defects of body casting during practical production were simulated by FLOW-3D software. The results show that the shrinkage defects are eliminated effectively by adding a gate on one side of casting defects,and at the same time making the corresponding adjustment to the riser size and distance. The production practice indicates that the plaster casting process can be optimized by computer simulation,which can conveniently and quickly solve the problems of casting.
