The device serves to cool rolls (10, 12), 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 (26) over a portion of roll surface (28). Spray devices are also provided for supplying a cooling medium (56) to parts of the roll surface. Liquid cooling medium (56) is collected and carried away in the lower part of hood (30). Hoods (30) are sealed off from the corresponding rolls (10, 12). A plurality of spray devices (32) in hood (30) serves to supply an at least partly liquid cooling medium (56) and extends axially over the entire length of the roll. Devices for removing liquid cooling medium (56) from roll surface (28) conduct the latter into a drain or suction device. Spray devices (32) and devices for removing cooling medium (56) are arranged individually or alternately in groups, with removal devices provided at both ends to remove cooling medium (56). Roll surface ( 28) is preferably cooled with increasing intensity in the direction away from roll nip (26).
A device for cooling the surfaces of a first and a second roll, each said roll rotating to form a nip between said rolls, said rolls useful in rolling metals or continuous strip casting, said device comprising:
In a device for cooling surfaces of a first and second roll, each said roll rotating to form a nip between said rolls, said rolls useful in rolling metals or continuous strip casting, said device having a first and a second hood, said first hood extending concentrically from the vicinity of the roll nip along a portion of said first roll, said second hood extending concentrically from the vicinity of the roll nip along a portion of said second roll, each said hood having a nip end and a downstream end, each said hood having a combination of spray means for supplying a cooling medium to said roll surface, first removal means for removing said cooling medium from said roll surface, and a drainage or suction device for removal of cooling medium collecting in the hood, wherein the improvement in each hood comprises:
