摘　　要：对压水堆核电站蒸汽发生器支承铸件用数值模拟的方法直接寻找铸件的热节位置,根据得到的热节数据设计冒口,并对设计的冒口进行数值模拟,直至得到最优结果。设计结果能够在保证铸件品质的前提下,节约金属材料,减少机械加工成本,提高铸造效益。The hot spots position of castings used for PWR nuclear power plant steam generator support was found out by numerical simulation method, and the riser was designed according to the data from the hot spot section. The numerical simulation was conducted for the designed riser, and the best results were obtained. The design results can save metal material, reduce machining cost and improve casting efficiency in the premise of ensuring the quality of castings.
