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.

Continuous casting plant for continuous casting of thin strip and method therefor

In a method of preventing contact of oxygen with a metal melt, metal melt flows into a casting chamber bounded by walls ( ) and leaves this chamber as a stream. In order to completely prevent contact of oxygen with a metal melt and thus reoxidation, oxygen attempting to enter via any gaps ( ) between the walls ( ) and/or adhering to the walls ( ) is reacted to form a compound which is not injurious to the metal melt ( ).

Method of preventing contact of oxygen with a metal melt

Method of preventing contact of oxygen with a metal melt during continuous casting, the metal melt flows into a casting chamber bounded by rolls and a hood and leaves this chamber as a stream. To completely prevent contact of oxygen with the metal melt and thus reoxidation, oxygen attempting to enter via any gaps between the walls and/or adhering to the walls is removed by suction applied at a succession of suction stages at the periphery of each roll before a gap between the hood and the roll at the top of the casting chamber. Inert gas may then flow to the rolls near the gap.
