ABSTRACT:
In rolling, particularly cold rolling of sheets, control of roll camber, and hence of the flatness of the rolled sheet, is ensured by a device fitted with a distributor capable of delivering a thin, continuous, low-turbulence jet of cooling liquid along a generatrix of the roll surface. The distributor is divided transversely into a number of chambers, each having structure allowing a given quantity of water into the chamber, this quantity being variable at will over a wide range. By regulating the quantity of water allowed into each chamber and hence the flow issuing therefrom, the amount of cooling along the body of the roll can be varied, thus varying its camber, so as to influence the flatness of the sheet.
