 bildung mit Sicherheit ein plötzliches Durchbrechen des Stahles zur wassergekühlten Spule hin ver- hindert. 



   Die Wandstärke der basischen Innenauskleidung kann gering gehalten werden, da auch bei
Verletzungen des basischen Innenfutters ein plötzlicher Durchbruch des Stahles nicht zu befürchten ist. Die Tiegelwände können daher dünn sein, wodurch ein hoher elektrischer Wirkungsgrad bei In- duktionsöfen erzielt wird. 



   Nach einem andern Vorschlag der Anmelderin, der jedoch nicht zum Stande der Technik gehört, kann die Innenauskleidung des Tiegels nach jeder Schmelze durch   Einfüllen   frischer Ofenbaustoff- masse zwischen Einsatzgefäss und Ofeninnenwand erneuert werden. Dieser Vorschlag bietet besondere
Vorteile bei der Auskleidung der inneren Tiegelwandungen mit basischer Ofenbaustoffmasse nach der vorliegenden Erfindung, da eine fast unbegrenzte Haltbarkeit der basischen Innenwand erreicht wird. 



   Die Erfindung schafft somit die   Möglichkeit,   auch grosse Einheiten kernloser Induktionsöfen mit einer basischen Zustellung zu betreiben, und weist darüber hinaus den grossen Vorteil der Verhütung von Unfällen auf.

 formation prevents the steel from suddenly breaking through to the water-cooled coil.



   The wall thickness of the basic inner lining can be kept low, as also with
Injuries to the basic inner lining, a sudden breakthrough of the steel is not to be feared. The crucible walls can therefore be thin, as a result of which a high electrical efficiency is achieved in induction furnaces.



   According to another proposal by the applicant, which does not belong to the state of the art, the inner lining of the crucible can be renewed after each melt by pouring fresh furnace building material between the insert vessel and the furnace inner wall. This proposal offers special
Advantages in lining the inner crucible walls with basic furnace building material according to the present invention, since an almost unlimited durability of the basic inner wall is achieved.



   The invention thus creates the possibility of also operating large units of coreless induction furnaces with a basic lining, and also has the great advantage of preventing accidents.

 

Claims (1)

PATENT-ANSPRUCH : Feuerfester Tiegel. von grossen kernlosen Induktionsöfen für basische Schmelzführung, dadurch gekennzeichnet, dass der Tiegel aus einem basischen Innenfutter und einem äusseren, um das Innen- futter angeordneten Schutztiegel aus einem Baustoff mit hoher Temperaturwechselbeständigkeit gebildet wird, der beim Reissen des basischen Innenfutters ein Durchbrechen des Stahles zur Spule hin verhindert. PATENT CLAIM: Refractory crucible. of large coreless induction furnaces for basic melting, characterized in that the crucible is formed from a basic inner lining and an outer protective crucible around the inner lining made of a building material with high thermal shock resistance, which breaks the steel to the coil when the basic inner lining ruptures prevented.
