It is crucial to limit the force link between the vertical and horizontal stands of a plate rolling mill implemented through the metal workpiece. Such rolling mills are often used for the formation of conical profiles at the ends of workpieces by moving the rollers during the rolling process. This results in the changing of instantaneous metal volumes at the vertical stand output and ...
