In this work, finite element simulation of the rolling-pressing process with horizontal and vertical rolls was carried out. To analyze the efficiency of metal processing, the main parameters of the stress-strain state were considered: equivalent strain, equivalent stress, average hydrostatic pressure, deformation force. Aluminum alloy Al6063 was chosen as the workpiece material. For variational simulation, models with a change in the heating temperature of the workpiece and the rolls rotation speed were constructed. The most optimal option is a model in which the workpiece was heated to 100 °C and deformation was carried out at a circumferential speed of the first pair of rolls of 60 rpm. Variants with a single temperature reduction to 20 °C, or rotation speed reduction to 35 rpm also give acceptable results to all the indicators considered. However, rotation speed reduction to 10 rpm makes it impossible to carry out a stable process at any temperature.
