Abstract: A cooled strand guide roller (1) mounted at more than one location for guiding a metal strand (S) in a continuous casting machine, and a method for cooling a strand guide roller (1) mounted at more than one location. An internally cooled strand guide roller (1) is mounted at more than one location. The height of the strand guide roller (1) is intended to be adjustable easily and quickly. The strand guide roller (1) has a collecting bar (7) for supplying the strand guide roller (1) with cooling water. The collecting bar (7) includes a plurality of brackets (10, 10a, 10b). Between two successive brackets (10, 10a, 10b), there is at least one coolant pipe (11) for fluidically connecting the brackets (10, 10a, 10b). An outer bracket (10a) has 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). 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).

Abstract: A method for semi-continuous casting of a strand of steel in a strand casting machine and a strand casting machine that carries out the method, the method includes pouring liquid steel into a mold while closing off the mold by a bar to form a fully solidified strand start area followed by a partially solidified strand; extracting the partially solidified strand from the mold; supporting and guiding the partially solidified strand in the strand guide; at the end of the casting, ending the pouring of liquid steel into the mold and forming a strand end; extracting the strand end from the mold; ending the extraction of the strand end; ending the secondary cooling; providing controlled or regulated cooling of the partially solidified strand until full solidification of the strand; and discharging the strand from the strand casting machine.
