ABSTRACT:
A roll for rolling mill, preferably a sag-compensating roll having hydrostatic support piston means, is provided with one or more heat-control devices each comprising a piston mounted in a chamber supported by the support beam of the roll and provided with an operating plate facing the inner surface of the roll shell. The surface of the operating plate has grooved ducts connected with the interior of the chamber to supply heat-control liquid to a thin gap produced between the operating plate and the roll shell. Such ducts may terminate short of the boundary of the plate and intermediate ducts may extend to the boundary. With a plurality of heat-control devices spaced in a row, overlapping oblique parallelogram plates may be employed, with connecting pins to prevent relative rotation therebetween.
