Abstract

PURPOSE:To quickly control the meander of a sheet material over a wide range, by detecting the meandering extent of the sheet material in a continuous treating apparatus, and by regulating the sheet shape in a following rolling work so as to restrict the meander correspondingly to the detected meandering. CONSTITUTION:The meandering extent (a) of a sheet material S held on a hearth roll is detected by a meander detector; a control object selector 15 selects the maximum one among meandering extent (a) detected at various points. The selected signal (b) is inputted to a comparator 16 which then compares it with an aimed value (d). A signal (e) outputted from the comparator 16 is arithmetically processed by an aimed shape operator 17 which then determines the aimed shape (f). On the other hand, a shape detector 19 detects the shape of a rolled sheet material S on the run-out side of a continuous cold rolling apparatus; the detected shape (g) is compared by a comparator 18 with the signal (f) sent from the aimed shape operator 17. A control action signal (h) outputted from the comparator 18 is inputted to a controller 20 which then outputs an action signal (i); a required roll crown corresponding to this action signal (i) is given to a work roll so that the sheet material S is rolled into a shape restricting the meandering extent.
