Casting wheel

The invention relates to a casting wheel for the continuous casting of strips of metal, preferably strips of ferrous metal within a thickness range between 1 mm and 12 mm, comprised of a core and a sleeve made of heat-conductive material, which is shrunk on the core, circumferential cooling ducts being located between the core and the sleeve, which are connected with coolant supply and discharge lines. A casting wheel for the continuous casting of strips of metal has a core and sleeve of heat-conductive material which is shrunk on the core, and circumferential cooling ducts arranged between the core and the sleeve, which are connected with coolant supply line and coolant discharge line. The coolant is guided from the radially extending supply line into cooling ducts and from cooling ducts into the radially extending discharge line by means of a guiding element that can be inserted in cooling ducts.
