The numerical simulation technology of sand casting process is a simulation technology method that combines numerical analysis, database technology and visualization technology and is comprehensively applied to the molding process of sand casting. It integrates various disciplines, including heat transfer, phase transition dynamics and so on. The flow field and temperature field during mold filling and solidification of sand castings are obtained by simulation to predict the defects of sand castings.
Through the numerical simulation of sand casting process, we can carry out simulation calculation for different processes before metal casting, compare and analyze the advantages and disadvantages of each process, optimize the process through computer simulation results, put forward correction schemes for existing problems, and obtain high-quality sand castings. Numerical simulation technology can not only improve production efficiency and reduce cost, but also reduce environmental pollution and waste of resources.
The numerical simulation of sand casting process includes the simulation of mold filling process and solidification process. The physical fields involved in the calculation are different, so the mathematical models are also different.
