ABSTRACT:
The device proposed herein incorporates the following components located on both sides of the roll mill stand: hydraulic dynamometers for absorbing the rolling force; hydraulic cylinders for creating and exerting the adjusting force; and valves for oil pressure control in the hydraulic cylinder interior. The hydraulic dynamometers are situated between the supports of one of the rolls and the roll mill stand housing and the hydraulic cylinders are interposed between the supports of the other roll and the roll mill stand housing.
The interior spaces of said cylinder and the dynamometer communicate with pumping units that deliver oil thereto so as to build up a pressure in the spaces which is in excess of the rolling force. The valves regulate the pressure effective in the hydraulic cylinder interior in direct proportion to the rolling force and the deforming force of the elastic members of the device.
