Current Status and Development Trend of Casting Numerical Simulation Technology

In this paper, the current status of the casting numerical simulation technology was introduced in two aspects: the practical technologies and the developing technologies. From the application of the typical cases, we can conclude that the casting numerical simulation technologies ofsolidification, mold filling, mold filling with heat transfer have entered the practical stage and can havea satisfying application in different casting method, such as gravity casting, low pressure casting, high pressure casting, and also for different alloys, such as steel, iron, nonferrous alloys. The other casting numerical simulation technologies including the stress-strain, microstructure, property, lost foam, core formation, segregation, melting, heat treatment, etc. also have a good development. Combing with theactual needs of the foundry industry, this paper points out that the high-precision quantitative prediction technology of the defects, the reverse technology of the thermophysical parameters, the design and optimized technology of intelligence casting process, and the integration of the whole casting processof simulation and the casting digital management are the development trends of the casting numerical simulation technology.
