Abstract
The invention relates to a casting roller (1), for a double-roller continuous casting machine, in particular for the casting of a steel strip, comprising a cylinder sleeve (2) which may rotate about a fixed axle (5). Intermediate rings (7b, 7c, 7d) rotating with the cylinder sleeve (2) are arranged between the cylinder sleeve (2) and the axle (5), which are provided with radial pressure means (9), acting on the cylinder sleeve (2). The above comprise a pressure chamber (10), pressurized with a fluid pressure medium and acting on a pressure ring (24) fixed to the inner wall of the cylinder sleeve (2), which may be deformed in the radial direction by inductive heating or radiated heat. The external profile of the casting roller (1) may be globally altered or local fine adjustments made by pressurizing the pressure chamber (10) with the pressure medium, or by heating the pressure ring (24).
