Abstract

PURPOSE:To always maintain the interstand tension at the target value, on purpose to perfectly prevent the misroll, by installing the controller for controlling the rolling speed of the stand according to the signal received from the tension detector and the tension setter installed in the upstream stand, and by installing the straightening guide at the down stream side of the work roll in the upstream stand.
