摘　　要：采用铸造模拟软件ProCAST,针对40T金属模钢锭的传热凝固过程,选用不同的模型剖分方式(全模型、1/2模型、1/8模型),研究模型剖分方式对凝固计算精度及效率的影响。结果表明:模型选取越小,会降低计算精度,太大则会增加计算内存的使用量。综合考虑,对于大型钢锭的传热模拟计算,建议使用1/2模型进行计算。Casting simulation software ProCAST was adopted to select different model subdivision methods (full model, 1/2 model and 1/8 model) for the heat transfer and solidification process of 40 tons metal mold ingot. The influence of model subdivision on solidification accuracy and efficiency was studied. The results show that the calculation accuracy will be reduced if the model is too small;the memory usage and calculation time will increase dramatically if the model is too large. Overall, it is suggested to use the 1/2 model for the heat transfer simulation calculation of large steel ingot.
