To the solution problems of contact interaction in a two-roll module

Abstract

Abstract The basic problems of the theory of contact interaction in a symmetric two-roll module are solved. Mathematical models of roll contact curves, friction stresses and distribution patterns of contact stresses in a symmetric two-roll module are obtained. Expressions that determine the indices of the roll contact curves in a symmetric two-roll module are derived. It was revealed that the neutral point in the drive roll is to the left of the centerline, and the maximum point of the diagrams of normal contact stresses does not coincide with the neutral point and is either in the no-slip zone or in the backward slip zone.
