ABSTRACT The device serves to cool rolls, especially in continuous strip casting and in rolling metals. The rolls are covered by hoods, each of which extends from the vicinity of roll nip over a portion of roll surface. Means are also provided for supplying a cooling medium to parts of the roll surface. Liquid cooling medium is collected and carried away in the lower part of hood. Hoods are sealed off from the corresponding rolls. A plurality of spray devices in hood serves to supply an at least partly liquid cooling medium and extends axially over the entire length of the roll. Means for removing liquid cooling medium from roll surface conduct the latter into a drain or suction device. Spray devices and means for removing cooling medium are arranged individually or alternately in groups, with means provided at both ends to remove cooling medium. Roll surface is preferably cooled with increasing intensity in the direction away from roll nip.
