Abstract

PURPOSE:To improve the accuracy in control of sheet flatness by providing means for calculating the correction quantity for roll bending from the edge waviness and middle waviness of a material to be rolled on the outlet side of a rolling mill and executing feedback control. CONSTITUTION:The output from a flatness detector 6 on the outlet side of the rolling mill 5 is inputted to the 1st arithmetic unit 7 by which the edge waviness E and middle waviness C are outputted. The deviation signal eE between the edge waviness E and a target value is inputted via a dead zone 8 to the 2nd arithmetic unit 9. The deviation signal between the middle waviness C and the target value is inputted via a dead zone 12 to the 3rd arithmetic unit 13. The outputs UE, UC from both units 9, 13 are inputted respectively to the 4th and 5th arithmetic units 16, 17. The correction quantity DELTAFw for bending force of a work roll is obtd. by the addition of the output UE from the unit 9 and the output U12 from the unit 17 and is fed to a control device 18 for the bending force of the work roll. The correction quantity DELTAFi for the bending force of an intermediate roll is obtd. by addition of the outputs UC and U21 from the units 13, 16 and is fed to a control device 19 for the bending force of the intermediate roll.
