Abstract
A method of controlling a tension levelling equipment for correcting residual distortions in an extension of strip including a series of input and output bridle roll means for rendering a tension upon the extension of strip extending between the input and output sides of a levelling mill station for smoothing out the distortions, and slipping clutch means connecting the bridle roll means with driving means allowing a slipping motion therebetween, which comprises the steps of measuring a current tension rendered upon the extension of strip at both the input and output sides of either of the input and output bridle roll means, and controlling the engaging torques of the slipping clutches in such a manner that a current slipping motion produced between the extension of strip and the bridle roll means may be nullified or eliminated according to the result of measurement of tensions, whereby it can remove all possible defects such as flaws and scratches in the surface of a strip product caused from the slipping motions as encountered during the passing through the tension leveler, thus contributing a substantial improvement in the surface condition and quality of the strip product.
