<p>PURPOSE:To reduce L camber in the longitudinal direction of strip by arranging auxiliary rolls on the outlet side of a cold rolling mill, estimating the L camber by detecting the strip quantity in a coiling reel and adjusting the positions of auxiliary rolls based on calculated values by operating the working quantity of the auxiliary rolls. CONSTITUTION:A metallic strip 2 which is delivered from a payoff reel 1 is supplied to skin pass rolling mills 4, 5 through the bridle roll 3 on the inlet side and, after the metallic strip 2 is applied a reverse camber with an anticlipping roll 6 and anticorrugating roll 7 which are arranged on the outlet side of the skin pass rolling mill 5, the metallic strip is coiled with the coiling reel 10 through the bridle roll 9 on the outlet side. At this time, the revolving speed of the coiling reel 10 is detected with a tachometer. The detected value is compared with set value with an arithmetic device 13 and a necessary control signal is output to a controller 12. A driving means 8 is controlled with the controller 12 by inputting the control signal based on the measured value and set value 14 from the arithmetic device 13. The anticorrugating roll 7 is vertically moved with the driving means 8.</p> |
