Currently, there is a steady demand for flat-shaped ingots (FSI) made from 5083 aluminum alloy grade. During rolling due to plastic deformation, “healing” of various casting defects, including pores, is possible. Therefore, FSI without subsequent rolling should have a regulated pore size of not more than 60 microns. To solve this problem, the authors carried out studies of the formation of porosity in the FSI volume during semi-continuous casting directly under industrial conditions at one of the UC RUSAL metallurgical plants. This made it possible to determine the influence of technological regimes on the formation and distribution of porosity in the FSI volume and to improve the technology of their production, guaranteeing the achievement of the required porosity parameters.
