 wo sie aneinander gesteckt werden, wodurch Bruch entstehen kann, bevor die Elektrodenspitze bis   zu   der Ansteckungsstelle vollständig ausgenutzt ist. 



   Die Ausführung der Erfindung ist von der Form des Ofenraumes und der Zahl der Elektroden und Tiegel ganz unabhängig.   Zweckmässig   ist eine Ausführungsform, bei welcher eine der Zahl der Elektroden entsprechende Anzahl von Tiegeln symmetrisch zu den Elektroden angeordnet ist. 



   Das Kontaktmaterial der Absätze kann mit einer gemeinsamen elektrischen Leitung verbunden und an die Stromquelle der Elektroden angeschlossen werden. 



   Statt des Kontaktmateriales oder auch in Verbindung damit können besondere, z. B. horizontal angeordnete und bewegliche Seitenelektroden in solcher Weise angeordnet sein. dass ein Lichtbogen zwischen einer lotrechten und einer entsprechenden horizontalen Elektrode gebildet werden kann. Die Seitenelektroden können untereinander verbunden werden ; es können aber auch die lotrechten Elektroden untereinander verbunden und die Seitenelektroden an die Stromquelle, beispielsweise an einen Transformator, angeschlossen werden. 



   PATENT-ANSPRÜCHE : 
 EMI2.1 
 sich die kleinstückige Masse auf Absätzen befindet, die von der Seitenwand des Ofens in dessen Inneres soweit vorspringen, dass in der Mitte des Ofens für das Schmelzgut, für Tiegel od. dgl. Raum bleibt.

 where they are plugged together, which can cause breakage before the electrode tip is fully used up to the point of infection.



   The embodiment of the invention is entirely independent of the shape of the furnace space and the number of electrodes and crucibles. An embodiment is expedient in which a number of crucibles corresponding to the number of electrodes is arranged symmetrically to the electrodes.



   The contact material of the paragraphs can be connected to a common electrical line and connected to the power source of the electrodes.



   Instead of the contact material or in connection with it, special, z. B. horizontally arranged and movable side electrodes can be arranged in such a way. that an arc can be formed between a vertical and a corresponding horizontal electrode. The side electrodes can be connected to one another; however, the vertical electrodes can also be connected to one another and the side electrodes can be connected to the power source, for example to a transformer.



   PATENT CLAIMS:
 EMI2.1
 the small-sized mass is on shoulders that protrude from the side wall of the furnace in its interior to such an extent that space remains in the middle of the furnace for the melting material, for crucibles or the like.

Claims (1)

2. Abänderung des Ofens nach Anspruch 1, dadurch gekennzeichnet, dass das Kontaktpulver durch eine oder mehrere, zweckmässig durch die Seitenwand eingeführte, horizontale oder etwas geneigte, vorzugsweise bewegliche Elektroden ganz oder teilweise ersetzt ist, die untereinander oder an die Stromquelle angeschlossen sind. 2. Modification of the furnace according to claim 1, characterized in that the contact powder is wholly or partially replaced by one or more, usefully introduced through the side wall, horizontal or slightly inclined, preferably movable electrodes, which are connected to one another or to the power source. 3. Ofen nach Anspruch 1 und 2, dadurch gekennzeichnet, dass eine der Zahl der Elektroden entsprechend Anzahl von Tiegeln symmetrisch zu den Elektroden angeordnet ist. EMI2.2 3. Furnace according to claim 1 and 2, characterized in that one of the number of electrodes corresponding to the number of crucibles is arranged symmetrically to the electrodes. EMI2.2
