With the increasing maturity of computer technology, casting simulation software tends to be improved. Casting numerical simulation technology has become the third important method to solve actual casting defects after empirical judgment and experimental analysis. Casting CAE technology is more comprehensive and detailed than experimental and theoretical methods. The continuous development of casting industry also puts forward higher requirements for casting numerical simulation technology. The future casting simulation technology mainly has the following development directions:
(1) Oxidation inclusion simulation. The oxides that may be mixed in castings mainly include MnO, Al2O3, SiO2, etc. based on the complex metallurgical principle and multiphase liquid flow theory, the location of oxide inclusions that may occur in the casting process is predicted and judged.
(2) Complex multiphase flow simulation. More truly simulate the liquid flow state affected by multiphase turbulence, surface tension, heat interaction and other factors in the process of pouring and mold filling.
(3) Microscopic numerical simulation. Since the development of numerical simulation of casting process, almost all the relevant research has focused on the macro scale. Because the micro dendrite growth and nucleation is a very complex process, it is necessary to comprehensively consider the effects of more segregation, convection and temperature field in order to simulate the micro. At present, the main micro simulation models include cellular automata model, phase field model, Monte Carlo method and so on.
(4) In depth mechanism simulation. With the help of computer simulation software, the structure formation and properties of castings are controlled by deterministic method, probability theory method or phase field method.
