   Auch bei dem dritten Ofen kann Frischgas durch einen Generator G zugeführt werden. 



  Ebenso kann auch Frischluft durch Rekuperatoren   Z bezw. Z zugeführt,   werden, je nach den besonderen- Aufgaben. 



   Ofen III ist in bekannter Weise durch R2 an die Esse angeschlossen. 



   Zur Regulierung des Zuges im Ofen   I   ist ein kleiner Verbindungskanal m zwischen dem Ofen   I   und   11   vorgesehen.

1. Verfahren zum Glühen von Blechen mittels Gasfeuerung in reduzierender Atmosphäre, gekennzeichnet durch die Anwendung eines Ofens mit mehreren hintereinander geschalteten Kammern, wobei die Verbrennungsgase jeder Kammer unter Zuführung regelbarer Mengen Frischgas in die nächste Kammer geleitet werden, um sie daselbst mit beliebig herabgesetzter Temperatur auf die Bleche einwirken zu lassen, und die Abgase der letzten Kammer entweder zum Schornstein geführt oder aber unter Zuführung von Frischluft zu beliebigen Zwecken ausgenützt werden.

   A generator G can also supply fresh gas to the third furnace.



  Fresh air can also be used through recuperators Z respectively. Z are supplied, depending on the particular tasks.



   Oven III is connected to the chimney in a known manner through R2.



   To regulate the draft in furnace I, a small connecting channel m is provided between furnace I and 11.
 EMI2.1
 
1. A method for annealing sheet metal by means of gas firing in a reducing atmosphere, characterized by the use of a furnace with several chambers connected in series, the combustion gases of each chamber being fed into the next chamber with the supply of controllable amounts of fresh gas in order to raise them there with any reduced temperature to let the sheets take effect, and the exhaust gases from the last chamber either led to the chimney or, with the supply of fresh air, used for any purpose.
