Abstract：The casting process of half-ring plate was simulated and predicted,and the sand mold casting process and casting defects were studied.Based on the analysis of the structure,technical requirements and technical difficulties of the medium half-ring plate,the technological scheme was designed.In addition,the 3 D model of casting was established by using Pro/E,and the filling and solidification processes of the half-ring plate were simulated by AnyC asting software,and the possible defects were analyzed.According to the simulation results of temperature field and defect distribution,the process scheme was optimized.The results show that there is a high probability of shrinkage porosity and shrinkage cavity near the riser on the bottom surface of the casting.By changing the solidification sequence of the chillers,the shrinkage effect of the risers is improved,and the casting quality is improved without shrinkage defects.
