The Work Roll Bending Control System of the Hot Plate ...
A majority of modern rolling mills to eliminate the roll bending value during the operation, are equipped with a work roll bending system (WRBS) [4]. WRBS has a hydraulic cylinders at the roll edges, which create a compensation force. The value of this force must convert the bending curve into constant roll-gap.
