SUBSTANTIATION OF TECHNOLOGICAL MODES OF PROCESSING CRYSTALLIZING METAL BY PRESSURE USING THE PROCAST SOFTWARE PRODUCT

The possibility of modeling the casting process with crystallization under pressure in the ProCast software package is considered. Simulation results are compared with experimental values. The study of the process is carried out on a horizontal hydraulic press, using technological equipment for the production of cylindrical blanks Ø90× 70 mm. The stages of modeling include a sequence of actions: preparing the geometry of the 3D model of the foundry block; drawing a surface grid using the functions sewn into the program; determination of thermophysical properties and setting boundary conditions. Using solvers, the filling of the mold and the temperature distribution in the mold, taking into account the pouring time, were simulated. In the work, the distribution of macroporosity inside the casting was calculated. Comparing the simulation results and the data obtained experimentally, it is concluded that the ProCast software product is adequate and can be used to solve scientific and applied problems
