By use of orthogonal test design, how the injection speed, pouring temperature and mold temperature effects the castingshrinkage porosity forming is studied.
然后，本文通过正交试验的方法研究了压射速度、浇注温度和模具预热温度对铸件缩松缩孔缺陷的影响。

Based on calculated temperature distribution in the casting, the prediction of shrinkage defects can be achieved, which can be used as a tool to optimize the design of foundry technology.
基于温度场分析结果的铸件缩孔缩松预测可以优化铸造工艺设计。
