description: This work was done in order to improve the quality of the casting during directional solidification. The paper discusses the use of 3D modeling of casting processes using specialized programs to prevent the production of defective castings during mass production. The aluminum alloy of the AlSi17Cu4.5 system was selected for the study. The task of the research is to compare the results of the influence of the temperature of pouring the melt with temperatures of 680, 700, 750 and 810 Â° C in the form of a coil and sandy clay on the process of solidification of the shaped casting. And also a comparison of studies of the influence of the mold material on the process of solidification of the casting (at a mold temperature of 25 Â° C) and heating of the molds to 150 and 300 Â° C. The modeling process was carried out in the program Polycast. Purpose of the program: modeling of hydrodynamic, heat and shrinkage processes during filling of the mold with melt, solidification and cooling of the casting. In the manufacture of large castings, the most important element of the casting technology is topping up profits, which determines the thermal regime, the processes of feeding the casting and the formation of dense metal, as well as the yield as an economic indicator of the quality of the developed casting technology. Work has been done to determine the parameters of topping based on the synthesis of production or experimental data and can only be considered as rough estimates that do not take into account the possibility of using new materials and technologies. Numerical methods allow to solve this problem on the basis of the initial (that is, without simplifications, characteristic of analytical solutions) differential equation of non-stationary heat conduction with the corresponding boundary conditions. The objective of the study is to examine the amount of the solid phase using the shrinkage porosity education program, the duration of directional solidification, and, based on the data obtained, to offer recommendations on the use of profit topping.
