Abstract：
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.
