| Abstract: | The numerical simulations of mold filling and solidification process for the YL112 aluminum alloy were done by the supposed mathematical model.The casting defects in the process of mold filling and solidification were predicted by the result of the casting simulation. The casting defects of simulation are well compared with the practice.Some measures presented were improved for the existing technological process. |
