Abstract
PURPOSE: To make the pass characteristic of plate stable and make control effective by determining the maximum value of plate crown control amount based on shape blind zone and distributing the control amount within that range thereby performing the plate crown control.
CONSTITUTION: In rolling, the deformation resistances obtained from the width, thickness, steel kinds, temperature, etc. necessary for determining shape absolute blind zone are sent to a setter 9 by the signal from a rolling condition operating setter 8. From these values, the blind zone is operated by an arithmetic unit 10. Next, from this value, the maximum value of plate crown control amount is determined and within this range the control amount is distributed to the double chock work roll bending devices 7 of the respective stands. In this case, the degree of permissible shape is larger as it goes toward the upper stream stands and therefore the practicable blind zone may be widened and the plate crown control amount in the upstream stands may be correspondingly increased.
