In einfacher Weise kann man jedoch die Schutzschlicht dadurch herstellen, dass man einem   sauerstoffhaltigen   Metallbade Aluminiumlegierungen in genägenden Mengen zusetzt, indem sich alsdann bei der Desoxydation des Bades Tonerde   und Tonerdesililate bilden, welche sich     an den, mit dem   Bad in Berührung kommenden Wänden festsetzen und letztere vor der schädigenden 
 EMI2.1 
 



   Unter Umständen, wie lange Betriebsdauer, hohe Temperatur usw. wird der so erhaltene Niederschlag von Tonerdesilikat oder Tonerde mit dem Zustellungsmaterial Aluminate bilden 
 EMI2.2 
 Aluminate   beeinträchtigen aber natÜrlich   infolge   ihrer speziellen Eigenschaften keineswegs   die beabsichtigte Wirkung. 



   Den wirksamsten Schutz erreicht man aber in einfachster Weise dadurch, dass man einem siliziumarmen,   saue1'8totthältigen   Einsatze Aluminiummetall in angemessener Menge zusetzt. 



    Hindurch wird bewirkt,   dass den mit dem Bad in Berührung stehenden Flächen annähernd reine Tonerde festhaftend anlagert und die   Wandungen des Schmelzramnes   gegen die Einwirkung des Bades schützt. Hat die   Schicht dieser Tonerdeansätze @ie gewünschte Stärke erreicht,   so kann dann in dem   Schmelzofen   ein siliziumreielherer Einsatz verarbeitet und weiterhin   auch ein     durch andere Mittel   als wie Aluminium oder Aluminiumlegierungen   wirkendes Desoxydations-   verfahren   benützt werden.   



   PATENT-ANSPRUCHE :   1.   Verfahren   zur Erhöhung   der Haltbarkeit der in üblicher Weise hergestellten Zustellung von Schmelzöfen, dadurch gekennzeichnet, dass man den sauer oder   basisch zugestellten Schmelz-

 einem Aluminat, oder einem Gemisch dieser Stoffe versieht, wobei dieser Überzug auch andere Körper, wie Eisen, Mangan usw. oder deren Verbindungen, in geringen Mengen enthalten   kann.

In a simple way, however, the protective coating can be produced by adding aluminum alloys in sufficient quantities to an oxygen-containing metal bath, in that the deoxidation of the bath then forms alumina and alumina silylates, which adhere to the walls that come into contact with the bath and the latter in front of the injurious
 EMI2.1
 



   Under certain circumstances, such as long operating times, high temperatures, etc., the resulting precipitate of alumina silicate or alumina will form aluminates with the lining material
 EMI2.2
 However, aluminates do not affect the intended effect of course due to their special properties.



   The most effective protection is achieved in the simplest way by adding an appropriate amount of aluminum metal to a low-silicon, dead-containing insert.



    This has the effect that almost pure clay adheres firmly to the surfaces in contact with the bath and protects the walls of the enamel rim against the effects of the bath. Once the layer of these alumina deposits has reached the desired thickness, a silicon-based insert can then be processed in the melting furnace and a deoxidation process using other means than aluminum or aluminum alloys can also be used.
