Numerical Simulation of Mold Filling and Solidification Behavior in Permanente Casting Process

摘要：

　　Melt flow and casting solidification are essential parts of the permanent mold casting process and affect significantly the quality of castings.For this reason,accurate prediction of mold filling pattern and temperature field in permanent mold castings plays on an important role in producing sound castings.In this paper,the model filling and solidification of a box casting produced from an aluminum alloy is studied.Different casting processes are employed,simulated and optimized to obtain sound castings.Simulation results reveal that with appropriate gating system,pouring rate,cooling line,a smooth mold filling,reduced shrinkages and other defects are available and desired sound castings can be produced.
