ABSTRACT:
In rollers, especially those used for continuous casting of strips (40) of aluminum and other metals, the coolant flows between the roller shell (7) and the roller core (8) through axial cooling channels (26). The counterflow principle is here applied, so that the coolant alternatively flows in the cooling channels (26) from one front side (41, 41a) to the other and is discharged there. A bore divided into an axial channel (15) and into a tubular channel (16) for supplying and discharging the coolant extends from one front side of the roller (1) to the other front side. Alternating supply and discharge ducts for the cooling channels (26) that extend over the whole length of the roller core (8) are arranged in such a manner near both roller front sides that the coolant flows according to the counterflow principle. The cooling channels (26) are formed of longitudinal grooves in the core (8) and shell (7) of the roller.
