 die Röhre hineinreicht. 



   Das Speiserohr 25 verhindert eine Zerstreuung des Erzes innerhalb der Arbeitskammer. 



  Die Elektrode   kann   mit einer Stromquelle ausserhalb des Lichtbogens verbunden werden, um zu verhindern, dass der Strom durch den Herdeinsatz selbst hindurchgeht. 



   Um anzuzeigen, ob zuviel Material auf den Elektroden sich befindet, ist ein elektrischer Kontakt J in der Wand der Arbeitskammer eingesetzt, der in Berührung mit der Spitze des Materialhaufens kommt, sobald dieser zu hoch wird, und dann einen Stromkreis 27 einer Alarmvorrichtung28schliesst. 



   Um die geneigten Elektroden 4 und B leicht verschieben zu können, sind dieselben auf einem Fahrgestell   K   gelagert, das auf einem von Ständern Mund N getragenen, geneigten Schienenweg L laufen kann und durch Treibscheiben 0 betätigt wird, die durch Seile mit einer von einem in geeigneter Weise gesteuerten elektrischen Motor Q angetriebenen Windetrommel P verbunden sind. Die Elektroden gleiten in der Wand der Arbeitskammer in der Weise, dass wohl genügend starker Kontakt zwischen beiden herrscht, ohne dass aber eine zu grosse Reibung entsteht.   Die Wandteile 28'über   den Elektroden sind vorteilhaft unter 90  gegeneinander angeordnet. Flüchtige Produkte werden aus dem Inneren der Arbeitskammer durch geeignete Kanäle 29 in den Seiten derselben abgeführt. 



   Zum Ausgleich des Eigengewichtes der Elektroden sind Gegengewichte S vorgesehen, die mit denselben durch über Rollen 31 laufende Seile ? verbunden sind. 



   Der Arbeitsvorgang ist folgender :
Das Material wird in fein verteiltem Zustande in den   Trichter I gebracht, gelangt durch   die Rohre 16 und   9. ; nach unten   und bildet einen Haufen über den Elektroden, die den Lichtbogen erzeugen, und über der Herdeinsatzelektrode. Der Lichtbogen reduziert aus dem ge-

 the tube extends into it.



   The feed tube 25 prevents the ore from scattering within the working chamber.



  The electrode can be connected to a power source outside the arc to prevent the current from passing through the stove insert itself.



   In order to indicate whether there is too much material on the electrodes, an electrical contact J is inserted in the wall of the working chamber, which comes into contact with the top of the material heap as soon as it becomes too high and then closes a circuit 27 of an alarm device 28.



   In order to be able to move the inclined electrodes 4 and B easily, they are mounted on a chassis K, which can run on an inclined rail track L carried by stands mouth N and is operated by traction sheaves 0, which are operated by cables with one of a suitable Way controlled electric motor Q driven winding drum P are connected. The electrodes slide in the wall of the working chamber in such a way that there is probably enough contact between the two, without creating too much friction. The wall parts 28 ′ above the electrodes are advantageously arranged at 90 ° to one another. Volatile products are discharged from inside the working chamber through suitable channels 29 in the sides thereof.



   To compensate for the dead weight of the electrodes, counterweights S are provided, which are connected to the electrodes by ropes? are connected.



   The process is as follows:
The material is brought into the funnel I in a finely divided state, passes through the tubes 16 and 9; down and form a pile over the electrodes that create the arc and over the hearth insert electrode. The arc reduces from the
