摘要： A method of correcting distortions existing in a rolled strip product by using a tension leveling equipment including a leveling mill station for smoothing out distortions remained in the strip product by producing a permanent elongation through the repetition of bending procedures rendered upon the strip while passing under tension therethrough, a pair of bridle units disposed on the both input and output sides of the leveling mill station, and means for rendering a tension upon the strip from a predetermined rate of elongation under the effect of a difference in the feeding velocities of the bridle units, which comprises the steps of detecting the distortions in the shape of the strip product upon the delivery thereof from the output bridle unit, obtaining detection signals, and controlling the rate of intermeshing in the leveling mill station and the rate of elongation of the strip product to a required range in accordance with the detection signals. With this improved method, it can afford a high precision correction of distortions in the strip product, following closely the possible fluctuations in the physical conditions which are generally particular to the strip product, thus making it possible in practice to obtain a high-quality strip product, accordingly.
