Abstract :
Mold filling and solidification of ZM5 shell were numerically studied by commercial software MAGMASOFT™. Casting parameters were optimized to reduce the extent of shrinkage porosity in the solidified shell. Calculated results show that the simulation results of the casting process with chills have a large amount of shrinkage porosity defects. Optimized casting process without chills can effectively eliminate shrinkage porosity defects, shrinkage defects can be effectively reduced.
