The present invention relates to a cooled strand guide roller (1) mounted at more than one location for guiding a metal strand (S) in a continuous casting machine, and to a method for cooling a strand guide roller (1) mounted at more than one location. The problem addressed by the invention is to specify an internally cooled strand guide roller (1) mounted at more than one location, said strand guide roller (1) being configured in a simple, robust and operationally reliable manner. Furthermore, the height of the strand guide roller (1) is intended to be adjustable easily and quickly. The solution is achieved by way of a strand guide roller (1) having a collecting bar (7) for supplying the strand guide roller (1) with cooling water, said collecting bar (7) comprising a plurality of brackets (10, 10a, 10b) and, in each case between two successive brackets (10, 10a, 10b), at least one coolant pipe (11) for fluidically connecting the brackets (10, 10a, 10b), wherein an outer bracket (10a) has in each case at least one first connection (8) for internal cooling of the cooled strand guide roller (1) and at least one second connection (9) for cooling the bearing blocks (4), and the first connection (8) is fluidically connected to the ducts (3) of the individual rollers (2a, 2b) and the second connection (9) is fluidically connected to the bearing blocks (4) via the brackets (10). |
