| Abstract: | The AnyCasting Casting Simulation Software was used to simulate the castings process of a nodular iron exhaust manifold cast with sand mold, to analyze its flow field and temperature field, and to forecast the defects that may occur in the casting, locations and sizes of defects. It was found that the results of simulation and analysis were basically in agreement with the experimental results. Hereby, the measures to improve the pouring rate and gate section area were proposed. Satisfactory casting was obtained after conducting test again with the improved casting method. |
