Patent ID: 8216117

Claim:
A method for cooling a roller device, which consists of a right bearing housing, a left bearing housing, and a roller, which is rotatably supported by journals in the bearing housings in continuous casting plants, in which a cooling medium cools bearings mounted in each of the bearing housings and passes through a central axial bore in the roller, the method comprising: introducing the cooling medium through a cooling medium inlet in a first of the bearing housings on one side of the roller device so that all of the cooling medium passes around the bearing mounted in the first bearing housing through bores arranged around the bearing in the first bearing housing; passing all of the cooling medium through the central axial bore in the roller; passing all of the cooling medium around the bearing mounted in a second of the bearing housings through bores arranged around the bearing in the second bearing housing, wherein the bores in the housings form a closed cooling channel; and then discharging all of the cooling medium from another side of the roller device through a discharge bore in an end face of the second bearing housing.
