Current trends in the development of metal forming methods are considered. Along with the increase in production volumes, the tasks of quality improvement, expansion of the product mix and energy costs reduction are becoming more and more important. To solve the set tasks, the most promising methods are combined processing, such as rolling-pressing, casting-rolling-pressing. The combination of different processing methods in one process allows conditions for the production of new profiles to be created, energy consumption to be reduced. However, the lack of sophistication of the issue in theoretical terms, the few experimental data make it difficult to find optimal modes of shaping and layout of equipment when combining processing methods. To determine the energy-efficient conditions of the rolling-pressing process, the rational layout of the equipment, new dependencies are proposed. Conducted analytical studies have proved that when implementing the rolling-pressing process for each deformation condition in the roll-matrix system, there is an optimal matrix installation location that provides the maximum drawing coefficient with minimal energy consumption. The feasibility range of the combined rolling-pressing process was established, energy-efficient deformation modes were determined, taking into account the design features of the deforming unit and the shape parameters. Recommendations for the rational layout of the deforming unit equipment, carrying out the rolling-pressing process were developed.
