 erkennt, von allen Seiten gleichmässig. Nach dem Glühen wird die Charge bis zur Höhe der Bahn h2   herabgelassen   und auf dieser abgeführt. 



   Die   Ausführungsform   nach Fig. 2 und 3 unterscheidet sich von der ersten Ausführung. form nur dadurch, dass die   Bahn 112   nicht die Verlängerung der Bahn h bildet, sondern unterhalb dieser Bahn in dem gleichen Kanal a angeordnet ist, so dass die geglühten Chargen an demselben Ende austreten, an welchem die frische Charge eintritt, und zwar unterhalb dieser letzteren. Die Ausbildung der Hebevorrichtung ist entsprechend etwas abzuändern. 



   PATENT-ANSPRÜCHE :
1. Ofen zum Glühen von   Metallgegenstanden   mit oberhalb der   Zu-und Abfohrungs-   kanäle gelegener Glühkammer, dadurch gekennzeichnet, dass die Zu- und Abführungskanäle als Vorwärme- und Kühlkammer dienen, und dass das Glühgut von unten her in die   Glüh-   kammer eingeführt wird.

 recognizes evenly from all sides. After the annealing, the charge is lowered to the level of path h2 and carried away on it.



   The embodiment according to FIGS. 2 and 3 differs from the first embodiment. form only in that the path 112 does not form the extension of the path h, but is arranged below this path in the same channel a, so that the annealed batches exit at the same end at which the fresh batch enters, namely below this latter . The design of the lifting device must be modified accordingly.



   PATENT CLAIMS:
1. Furnace for annealing metal objects with an annealing chamber located above the inlet and outlet channels, characterized in that the inlet and outlet channels serve as preheating and cooling chambers and that the annealing material is introduced into the annealing chamber from below.

Claims

2. Oven according to claim 1, characterized in that a seal is attached between the annealing material and the chassis for the annealing material, which seals the annealing chamber after lifting the Gltihgutem so that the chassis does not enter the annealing chamber.

3. Furnace according to claim 1, characterized in that the feed and discharge tracks for the annealing material are arranged one above the other in a common boiler, namely the feed track above, the discharge track below, whereby a very good heat exchange between the hot material below and the fresh charge above is achieved.

4. Furnace according to Claim 1 and 2, characterized in that the material to be annealed is fed in and out at one end of the furnace, so that the material to be annealed moves to and from the annealing chamber in opposite directions.
