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.

摘要： 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.

摘要： PURPOSE:To save a space and to increase the line speed in a coiling machine by providing a pair of rollers and a pair of clearance controlling means to press a slit material in a slit material coiling device. CONSTITUTION:Both edges of a steel strip W is cut and uniformized by a trimmer 101, its central part is divided by a slitter 102 into slit materials, Wa, WD and each pair of rollers 11a, 11D pressing slit materials Wa, WD from the top and the bottom are provided on a device to coil them by a coiling machine 105. Further, a means to detect, control the adequate positions of the slit materials, a clearance detecting device 2, a feedback controller 3 are installed to hold a prescribed clearance. Thus, it is possible to obtain a coil having a uniform plate edge by a coiling machine, to save the space and to reduce the cost.
