Parameters of roll contact curves of two-roll modules

Abstract

Analytical dependencies were obtained to calculate the lengths of roll contact curves, the lengths of the slip and no-slip zones, and angles that determine the position of the separation points of these zones. It was revealed that the slip zones asymptotically decrease to zero with an increase in the angle of inclination of the material to the line of centers. It was determined that an increase in the radii of the rolls and the projection of external forces on the axis, and a decrease in the projection of external forces on the axis led to an increase in the slip zone and a decrease in the no-slip zone.
