(1) The pouring temperature and other process parameters have an important impact on the internal structure of the sand casting material during the sand casting process. Due to the limitations of the software package and various actual conditions, the paper cannot carry out computer numerical simulation from the perspective of microstructure and other aspects to analyze and predict the final quality of the sand casting. In the future, the numerical simulation of the microstructure of the sand casting process material can be carried out to better understand the sand casting process.
(2) How to realize the concrete connection between the sand casting numerical simulation software ProCAST and the large-scale general ANSYS software, and make full use of the advantages of the two to realize the numerical simulation of the sand casting process and structure analysis, this work needs further research.
(3) It is very important and necessary to establish the physical property parameter database of common materials and improve the physical property parameters of PrOCAST. Although the software itself has a rich material property parameter library, it cannot meet the simulation of special use, and the accuracy of material property parameters has a great impact on the authenticity of the simulation. Therefore, it is very important to establish at least a targeted material property parameter library for sand casting process simulation.
To sum up, through the long-term theoretical research and practice of the subject, I realized the complexity and superiority of numerical simulation, and the importance of integrating theory with practice and analyzing problems. I hope that in the future, we can carry out progressive research on sand casting process optimization, make up for the lack of research in this paper, and make sand casting simulation technology better serve the actual production.
