Abstract
Rolls of a rolling mill have hydraulic pressure exerted on the exterior surfaces thereof by hydrostatic pressure devices which produce hydraulic pressure in the gaps between bearing surfaces of the devices and the roll, and a flow of the hydraulic fluid in the gaps to cool the rolls. The pressure may be applied to press the rolls together, and also to provide lateral support. Different pressures may be applied to devices spaced parallel to the roll axis. Quadrilateral and overlapping rhomboidal bearing surfaces may be employed. A pair of small diameter working rolls may be pressed together by larger diameter pressure rolls and lateral support provided for the working rolls.
