Modeling of Friction Stress in Twin Roll Modules

Abstract

Abstract The study is devoted to the analysis of the laws of the distribution of tangential friction stresses in twin roll modules. A two-roll module is considered, in which the rolls are positioned relative to the vertical by a slope to the right, have unequal diameters and elastic coatings from materials with different stiffness and friction coefficients, the material layer is sloped downward relative to the center line. Formulas are defined for calculating neutral angles in the considered two-roll module. Dependencies between the forces acting in the rolls and the stresses distributed under the influence of these forces are established. It was revealed that these dependences do not change with a change in the angle of supply of the material layer to the line of centers and the angle of inclination of the upper roll relative to the vertical.
