为预估熔铸炸药凝固过程中装药内部温度场的变化和出现缺陷的位置，采用有限元程序ProCAST对RHT炸药的凝固过程进行数值模拟。以熔铸炸药RHT的凝固过程为研究对象，计算出装药内部的温度场分布，预测装药内部形成缩孔和缩松的位置，并与试验结果进行对比验证。结果表明：ProCAST程序能够准确计算出熔铸炸药凝固时内部缺陷的位置，可以用于炸药熔铸工艺的仿真设计。
為預估鎔鑄炸藥凝固過程中裝藥內部溫度場的變化和齣現缺陷的位置，採用有限元程序ProCAST對RHT炸藥的凝固過程進行數值模擬。以鎔鑄炸藥RHT的凝固過程為研究對象，計算齣裝藥內部的溫度場分佈，預測裝藥內部形成縮孔和縮鬆的位置，併與試驗結果進行對比驗證。結果錶明：ProCAST程序能夠準確計算齣鎔鑄炸藥凝固時內部缺陷的位置，可以用于炸藥鎔鑄工藝的倣真設計。

In order to studying the temperature field change and predicting the location of defect during casting explosive solidification process, the finite element program ProCAST was used to simulate the solidification process of the explosive RHT. Based on RHT solidification process, the interior temperature field distribution is calculated, and the locations of shrinkage cavity and shrinkage porosity are predicated. Then, validate it with test result. The results show that ProCAST program can precisely calculate the interior defect location, and it can be used for simulation design of casting explosive.
