| 摘 要： | 为了克服传统Ir坩埚铸造研究中需占用大量Ir和资金的缺点,作者采用有限元方法计算了3种不同尺寸的Ir坩埚在铸造过程中的温度场变化特点.通过对计算结果的分析,有效地预测了缩孔在Ir坩埚壁出现的位置、浇口处缩孔的位置和形状等特点,同时给出了Ir坩埚底部中心处在凝固过程中的温度与时间关系的曲线.对于Ir坩埚实际铸造过程的工艺制定和优化具有指导作用.

| Abstract: | In the present paper, the finite element method was used to calculate casting iridium crucible temperature field of three samples. The calculation results indicated that the method not only predicts perfectly the location of shrinkage hole in the wall, but also predicts the location and shape of shrinkage hole in the sprue of iridium crucible, The time dependence of temperature in the center of the iridium crucible bottom is given also Those results are important for establishing and optimizating the casting technology of iridium crucible. |
