description: The topic of the final qualification work: "Obtaining electrical contacts based on copper by rolling". The paper considers the possibility of using the rolling process instead of DGP at the stage of hot compaction of the BrX2 material. Preliminary calculations of the rolling parameters were made when switching to a different size. Tasks of the final qualification work: 1. Determination of materials that are suitable for electrical applications; 2. To estimate, calculate by engineering method the obtained energy-power parameters of rolling the billet; 3. Develop a method for preliminary calculation of the rolling parameters when switching to a different size. Identify the main characterizing factors. The material of the blank is BrX2. This bronze is heat-resistant, used for heat exchangers, for electrodes, is indispensable in production, as an anti-friction material. It has increased corrosion resistance. The rolling out with a spherical moving tool was chosen as the technology. The selected equipment meets the requirements of the technological process. â
