Abstract:
This paper has simulated numerically the 2D temperature field and stress field of main circle pump shell steel castings of nuclear power plant by finite element method,predicts the dispersed shrinkage,shrindage and hot hearing.The real dissecting pouring castings had the same results as the numerical simulation.At the same time the authors evaluat the molding design of the pump shell castings.
