Abstract
The invention is a rolling mill for flat-rolled products designed in a manner to substantially eliminate bending of the rolls under load with associated convexity of the roll gap and resultant tendency towards excess convexity of bar transverse profile. The rolling mill employs the partial cylindrical surface of the roll barrel itself in contact with a corresponding work roll bearing pad, rather than roll neck end bearings, as the main load bearing mill bearings, and supports this bearing against a transversely elongated hydrostatic cushion which distributes the reaction to the roll force uniformly along the length of the work roll. Pressure equalizing cylinders at the roll ends are also used to compensate for bending effects resulting from differences between length of the hydrostatic cushion and width of the bar being rolled. The mill is intended for application to hot and cold rolling of plate, sheet and strip products made of steel, aluminum, copper and like, either in a single stand or in tandem rolling mill applications.
