ABSTRACT:
A casting roll (11) on which to cast molten metal comprises central shaft (12), an outer circumferential wall (14) fitted over cylindrical mandrel (15) and roll end walls (16). Longitudinal wall (14) is cooled by water passed through longitudinal passages (22) in that wall. The cooling water is passed to and from passages (22) through passages (23) in the central shaft, radial passages (24) in the end walls (16) and transition passages (25) interconnecting the radial passages with the longitudinal passages. In order to promote cooling of the end corners (31) of the roll, transition passages (25) extend in smoothly curved bends into regions of the roll disposed both radially and longitudinally outwardly from the intersection directions of the longitudinal passages (22) and radial passages (24) so as to provide for water flow close to the roll comers (31) without formation of stagnation pockets.
