Аннотация: The article shows the effectiveness of system analysis based on Shubnikov-Curie symmetry principle, in solving problems of thermal effect on the molten liquid metal when it is solidified in a mold. It has been suggested that a binary axis, relative to the lateral surface, appears in the ingot structure. In accordance with the generalized structure of the billet, geometric structure of crystallites and crystallographic texture are determined by the influence of the thermal field during the crystallization of the melt. The thermal field is determined by the geometry of the mold and the structural features of its sprue and bottom parts. Analysis of the generalized structure of the field of physical activity allows us to optimize the properties of the cast billet for subsequent forming processes of semi-finished products for mechanical engineering. This is important for the performance characteristics of the finished products. It has been experimentally proved that the structure of the cast billet (distribution of grains in the material) undergoes changes in accordance with Shubnikov-Curie principles of symmetry, during the crystallization process in the molds of various sections. It affects the physico-mechanical properties of the cast billet, including the plastic deformation during further forming processes. © 2020, National Academy of Sciences of the Republic of Kazakhstan.
