Abstract

PURPOSE: To contrive the improvement of accuracy of breadth of the strip, by giving the pressure- and tension-corrective signals to the pusher and the coiler, depending on the signal from the first and the second breadth meters for measuring the breadth of the hot strip.
CONSTITUTION: The breadth of the strip 2 outgoing from the finishing mill 1 is measured by the first breadth meter 3, and the signal X1 is inputted to the controller 8. Then, the strip 2 is given with the pressure and tension by rollers 41AWC of the pusher 4; hereby, the strip 2 longitudinally elongates and also reduces its breadth. Next, to this, the breadth of the strip 2 is measured by the second breadth meter 5, and its signal X2 is inputted to the controller 8. As a result, the pressure corrective signal (f) is given to the hydraulic cylinder 42B, and the tension corrective signal (g) is given to the mandrel 72, both from the controller 8, on purpose to control the breadth of the strip to be the aimed value. According to this method, the hot strip with excellently accurate breadth can be manufactured.
