   PATENTANSPRÜCHE : 
1. Einrichtung zur Erzeugung eines Kreislaufes von flüssigem Metall, insbesondere zur Entgasung des Metalls, mit einem Entnahmebehälter und einem oberhalb desselben angeordneten, vorzugsweise an eine Evakuierungseinrichtung anschliessbaren Gefäss, einem Einlaufrohr und einem Auslaufrohr, die vom Boden des Gefässes an eine Stelle unterhalb des Metallspiegels im Behälter führen, wobei mindestens das Einlaufrohr eine

B.- which consists of a material that is specifically lighter than steel. Appropriately, an additional, z. B. cage-like bracket can be provided.



   PATENT CLAIMS:
1. Device for generating a cycle of liquid metal, in particular for degassing the metal, with a withdrawal container and a vessel arranged above it, preferably connectable to an evacuation device, an inlet pipe and an outlet pipe, which extend from the bottom of the vessel to a point below the metal level lead in the container, at least the inlet pipe a
 EMI2.1
 Inlet pipe (10) has an upper funnel-shaped part (14) which forms the seat for a closing body (22), which consists of a material that is resistant to attack by liquid metal and liquid slag and has good thermal shock resistance, in particular metal-ceramic material, and a higher spec.

   Weight than the circulating metal, in the case of steel a spec. Weight
