For modern hot rolling mills the typical hydraulic circuit was designed to control the roll bending force during rolling process. The most common operating modes of the roll bending system were studied: rolling, start and stop. The bending roll control system was designed in the form of functional blocks, connecting the actuators, sensors and sided subsystems of the rolling control.
