Abstract

Abstract: Shell investment casting of AlSi11 alloy was stimulated in this paper. The shell model of AlSi11 alloy casting was established using UG three-dimensional drawing software, and the solidification process of the inner material of the shell was numerically simulated based on the ProCAST software. The final analysis shows that the entire solidification process is solidified layer by layer, and the filling time of the material inside the shell is 14.70s. After solidification and cooling, the shrinkage volume of the internal defects of the material is 7.80 square centimeters, the average shrinkage rate is 17.90%, and the pore volume is 1.70 square centimeters. Through the simulation and analysis of the solidification process, not only can we find out the shrinkage cavities generated in the solidification process, but also can effectively reduce production costs and improve efficiency.
