| Abstract: |
| In order to solve the disk body casting produced by a certain factory defects problem. ProCAST was introduced to simulate the filling and solidification process of the disk body casting, and then the shrinkage cavity and shrinkage porosity defects were forecasted. On the basis of the simulation, the casting technology was improved. The defects such as shrinkage cavity and shrinkage porosity in the casting were reduced obviously and the eligible rate of the product was improved. The application shows that the software can help technologists to optimize casting process by forecasting casting defects during mold filling and solidification processes and instruct the production of casting. |
