Deformation heating processes under asymmetric rolling conditions are of primary importance for determining the final properties of rolled products and optimizing production processes. Computer and laboratory studies of metal deformation heating during asymmetric rolling were conducted. The main factors influencing material temperature were analyzed. Using finite element computer modeling, the deformation intensity and thermal state of the metal in the deformation zone were compared under symmetric and asymmetric rolling conditions. The effect of mismatched peripheral speeds of the upper and lower work rolls on metal temperature changes was demonstrated. To verify the obtained theoretical results, experimental rolling studies were conducted on a DUO 180 reversible rolling mill at geometric asymmetry values of 1.5–3.0. An additional heating of the metal by 10–13 °C in the deformation zone was experimentally confirmed. An analysis of new technological solutions for the use of additional deformation heating and gradient deformation distribution across the metal thickness in the deformation zone was performed when using asymmetric deformation in traditional sheet metal production technologies.
