Beschreibung
Zusammenfassung:The ring carrier (10) has a cooling duct part (12) firmly connected and together with a ring carrier part (11) to form a closed cooling duct (15). A gas-impermeable barrier layer (16) is integrated in the ring carrier part at the cooling duct. The barrier layer runs approximately parallel to a surface (14) of the ring carrier part pointing to the cooling duct part. The ring carrier part is made of a metallic material i.e. austenic cast iron with flake graphite. The cooling duct part is made of a steel sheet. An independent claim is also included for a method for producing a ring carrier. Die vorliegende Erfindung betrifft einen Ringträger (10) mit einem Ringträgerteil (11) und einem Kühlkanalteil (12), das mit dem Ringträgerteil (11) fest verbunden ist und zusammen mit dem Ringträgerteil (11) einen geschlossenen Kühlkanal (15) bildet. Erfindungsgemß ist vorgesehen, dass in das Ringträgerteil (11) eine zum Kühlkanal (15) hin gasundurchlässige Sperrschicht (16) integriert ist. Gegenstand der vorliegenden Erfindung ist ferner ein Verfahren zur Herstellung eines derartigen Ringträgers (10).
