    Elektrischer Induktionsofen.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 



   Bei der Anordnung nach Fig. 3 ist der primäre und sekundäre Teil auf demselben Schenkel des geschlossenen Weicheisenkerns   4   angeordnet. 



   Fig. 4 zeigt einen Querschnitt des letzteren nach Linie   in-il   der Fig. 3. 



    Die Spule aus dem mit einer starken Oxydschichte versehenen Aluminiumdraht verträgt eine Erhitzung bis über die Schmelztemperatur des Aluminiums.   



   PATENT-ANSPRÜCHE :
1. Elektrischer Induktionsofen, insbesondere zur Stahlherstellung, dadurch gekennzeichnet, dass die   Primärspule aus oxydisoliertem Aluminiumdraht,   gegebenenfalls mit Zwischenlagen aus feuerfestem
Material besteht.
