Abstract

PURPOSE:To control inlet and outlet side tensions to optimum values and let shape correction and draw-in prevention by interlocking inlet and outlet side bridle rolls mechanical-tight and driving the operating gear of connecting mechanism with an elongation rate motor. CONSTITUTION:Bridle rolls 3, 5 on the inlet and outlet side and the drive system of a skin-pass rolling machine 4 are interlocked by a shaft 6. The outlet side bridle roll 5 is connected to an elongation rate motor 10 by way of a differential gear 7 and the elongation rate of a strip S is maintained always constant by the deviation between the speed reference D of a setter 22 and the feedback signal c from a speed detecting generator 11c. The inlet side bridle roll 3 is speed-controlled by the control system which compares a reference signal Vs and the feedback signal A from a speed detecting generator 11a. A skin-pass rolling mill 4 is applied with screw-down while its inlet and outlet side tensions are being monitored with potentiometers 19, 20. Also said mill is speed-controlled by a mill drive motor 9 and its drive system. Thereby, the removal, etc. of the yield point elongation owing to annealing of the strip S are effectively and continuously accomplished.
