Wide use of aluminum alloys is determined by their technical, physical and mechanical properties. Aluminum and its various alloys are used in a wide range of heavy and light industry, both in machine building: tractors, cars and agricultural machinery, and in the aviation industry and shipbuilding. Especially during the war in Ukraine, the country's economy is in a critical state, the use of technologies that save the use of any materials is very expensive, including aluminum alloys, which is an expensive material. The coefficient of material use when using the technology we offer is 0,15...0,3, thanks to the use of a hot forming or rolling plant.
The application of the process of hot deformation of blanks makes it possible to use the effect on plasticity to the maximum. Since the deformation of heated workpieces is carried out by a tool heated to the same temperature or close to them. Such a scheme of hot deformation will reduce the effort due to the increase in the plasticity of the metal being processed. What happens due to the full flow of strengthening processes. Uniform deformation of the workpiece, in the absence of zones of difficult deformation and local overheating, ensures a good and comprehensive restoration of the structure. It was found that during hot deformation, the metal pressure on the rolls decreases by 1,8 or more times.
Currently, there are few works on researching the possibilities of hot rolling on small-sized installations, which are not inferior to the high-quality production of parts with strong characteristics and improved macro- and micro-structures and mechanical properties. Therefore, conducting research on the influence of heating temperatures of blanks and dies, the degree of deformation on the technological parameters of hot rolling of blanks in hot dies is an urgent task. The solution of which can lead to improvement of plasticity and reduction of deformation forces, improvement of the quality of blanks.
