Abstract

In this paper an probabilistic model of the friction phenomena on the work- back up rolls contact surface has been presented. It has been shown that such character of the disturbance in distribution of zones with static and kinetic friction. can be regarded as one of the sources of self-excited vibrations appearing in the system consisting of a rolling mill and a strip.
