Abstract

PURPOSE:To remove the sheet camber, and to improve the quality and yield of the rolled plate, by arranging the sheet camber measuring instrument, the independently adjustable screw down device, the roll gap set value arithmetic unit, the sheet gauge deviation arithmethic control, etc. CONSTITUTION:The rolling mill 1 possesses the screw down device 12 being possible to independently adjust the roll gaps at lateral both side edges; this rolling mill 1 is additionally provided with the measuring instrument 2 for measuring sheet camber of the rolled material T, and its measurements are inputted to the aim sheet gauge deviation arithmetic unit 3. This unit 3 is inputted with output signals produced from the load cell 14, the draft position detector 15, the length meter 16, the breadth meter 18, etc.; the unit 3 operates the aim gauge deviation at lateral both edges of the plate in the next rolling pass for making zero the sheet camber, for every specified reference position plotted along the longitudinal direction; then, the unit 3 produces a signal and inputs it to the arithmetic control 13. The arithmetic control 13 independently control the screw down devices 12 in order to make the actual sheet gauge deviation to coincide with above aim value; hereby, the generation of sheet camber is prevented.
