 vorzugsweise an der Austrittsseite, ein verstellbares Drosselorgan 7 beliebiger Art. Dieses wird zweckmässig während des   Glühvörganges   teilweise geschlossen, so dass nur eine geringe Gasmenge den Glühraum durchstreicht, vor und nach dem Glühen aber so weit geöffnet, dass ein   kräftiger Gasstrom   den Glühraum   durchspült,   um das Glühgut rasch abzukühlen. Durch entsprechende Einstellung des Drosseloganes lässt sich die Abkühlzeit des Glühgutes in weiten Grenzen beeinflussen und   überhaupt   der Ofen an   verschiedenes Glühgut und   verschiedene Glühprozesse weitgehend anpassen.

   Ausserdem kann bei geschlossenem Drosselorgan die Vorsatzmuffel während des Glühbetriebes   nachgefüllt   werden, ohne dass in den   Glühraurn   Luft eintritt. 



   Zur Beheizung des Behälters 3   können   die den Glühraum verlassenden heissen Gase dienen, indem sie etwa den Behälter 3 unter   Wärmeaustausch   bestreichen, wozu dieser z. B. im Bereich des Kanales 5 angeordnet sein kann. Verbrennbare Bestandteile der abziehenden   Gase können   zur Beheizung des Behälters 3 verbrannt werden. 



   PATENT-ANSPRÜCHE :
1. Elektrischer Glühofen, dessen Glühraum mit der Aussenluft unter Zwischenschaltung von Sauerstoff absorbierenden Einrichtungen verbunden ist, dadurch   gekennzeichnet, dass   diese Einrichtungen zugleich zur Erzeugung zusätzlichen Schutzgases dienen, das gemeinsam'mit dem Luftstickstoff dem   Glühraurn     zugeführt,   gegebenenfalls durch diesen hindurch geführt wird.

 preferably on the outlet side, an adjustable throttle element 7 of any type. This is expediently partially closed during the annealing process, so that only a small amount of gas passes through the annealing chamber, but before and after annealing it is opened so wide that a strong gas flow flushes through the annealing chamber to cool the annealing material quickly. By setting the throttle logic accordingly, the cooling time of the annealing material can be influenced within wide limits and the furnace can be largely adapted to different annealing material and different annealing processes.

   In addition, when the throttle element is closed, the attachment muffle can be refilled during the annealing operation without air entering the annealing chamber.



   To heat the container 3, the hot gases leaving the glow chamber can be used by brushing the container 3 with heat exchange, for which purpose this z. B. can be arranged in the region of the channel 5. Combustible components of the evacuating gases can be burned to heat the container 3.



   PATENT CLAIMS:
1. Electric annealing furnace, the annealing chamber of which is connected to the outside air with the interposition of oxygen-absorbing devices, characterized in that these devices also serve to generate additional protective gas, which is fed to the annealing chamber together with the nitrogen in the air, optionally passed through it.

 

Claims (1)

2. Elektrischer Glühofen nach Anspruch 1, dadurch gekennzeichnet, dass zur Absorption des Sauerstoffes und zur Herstellung des zusätzlichen Schutzgases glühende Kohle verwendet wird. 2. Electric annealing furnace according to claim 1, characterized in that glowing coal is used to absorb the oxygen and to produce the additional protective gas. 3. Elektrischer Glühofen nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Durchführung von Schutzgas durch natürlichen Zug, am einfachsten durch einen angebauten Kamin (6) erfolgt. 3. Electric annealing furnace according to claim 1 or 2, characterized in that the implementation of protective gas takes place by natural draft, most easily through an attached chimney (6). 4. Elektrischer Glühofen nach Anspruch 1, 2 oder 3, dadurch gekennzeichnet, dass die den Glühraum verlassenden Gase durch Wärmeaustausch oder Verbrennung zur Beheizung der vorgeschalteten Vorrichtung (Vorsatzmuffel 3) dienen. EMI2.1 EMI2.2 4. Electric annealing furnace according to claim 1, 2 or 3, characterized in that the gases leaving the annealing chamber are used by heat exchange or combustion to heat the upstream device (attachment muffle 3).
