Application of the software ProCAST in the casting of solidification simulation

For researching the influence of casting process on the quality of castings,the solidification simulation of casting is developed by computer.Composing modules and functions of the FEM software ProCAST are introduced and the defects of the casting process are simulated.We then present an example for the ProCAST software to instruct the design of casting process.Workflow of ProCAST is described.The shrinkage defects of castings cast by sand molding process have been predicted using FEM software ProCAST.The simulated result laid down a foundation for improving the cast technology of the castings.The parameters of pouring system and riser system are optimized.The optimized process improved the casting yields and decreased the costs.The simulation way and approach used in this paper can be seen as a guideline in the design of other casting processes.
