Abstract

PURPOSE:To control the width of a strip to be constant by detecting the width or the width deviation of the strip between the stands of a hot finishing mill and regulating the mill-motor speed of an upstream stand basing on the signal obtained by said detection. CONSTITUTION:The width-end position of a strip 2 is detected by disposing an edge-position detector 3 between the stands 1a, 1b of a hot finishing mill, and a sheet-width operation signal obtained from a sheet-width operator 4 is compared with a set sheet-width wignal 6 by a comparison operator 5 to transmit its deviation signal to a mill-motor control device 7. In the control device 7; an output signal corresponding to said deviation signal is transmitted to the mill motor 8a of the upstream 1a, and the tension between the stands 1a, 1b is controlled by regulating the speed of motor 8a. In this way, the width of a strip is controlled into consant.
