Vorrichtung zum Schmelzen von G-läsern und anderen oxydischen Substanzen mit Hilfe direkten Stromdurohganges Device for melting glass and other oxidic substances with the help of direct current continuity
Beim elektrischen Schmelzen von G-läsern und anderen oxydischen Materialien mit Hilfe des direkten Stmidurchganges ist es bei hochschmelzenden Zusammensetzungen schwierig, das Schmelzgefäß so weit zu erwärmen, daß ein Stromdurchgang erfolgt. Diese Schwierigkeit wird durch die Vorrichtung gemäß der Neuerung beseitigt. During the electrical melting of glass and other oxidic ones It is materials with the help of direct passage of stems in the case of high-melting compositions, it is difficult to heat the melting vessel to such an extent that there is a passage of current. This Difficulty is eliminated by the device according to the innovation.
Die Neuerung bezieht sich auf eine Vorrichtung zum Schmelzen von G-läsern und anderen oxydischen Substanzen mit Hilfe des direkten Stromdurchganges durch das Sehmelzgut in einer Schmelzwanne. Die neue Lösung besteht darin, daß mehrere haarnadelförmige Elektroden in engem Abstand voneinander im Inneren der Schmelzwanne angeordnet sind und daß die Elektroden von wassergekühlten Halterungen in der Wand der Schmelzwanne gehalten sind. Als Elektrodenmaterial eignet sich z.B. Wolfram oder Molybdän.The innovation relates to a device for melting glass and other oxidic substances with the help of the direct Current passage through the Sehmelzgut in a melting tank. The new solution is to have several hairpin-shaped electrodes are arranged at a close distance from each other in the interior of the melting tank and that the electrodes of water-cooled brackets are held in the wall of the melting tank. Tungsten or molybdenum, for example, are suitable as electrode material.

In Figur 1 ist die haarnadelförmige Elektrode 11 durch wassergekühlte Halterungen 12, die gleichzeitig zur Stromzuführung dienen, in der Wandung 13 der Schmelzwärme gehalten und reicht in das Innere der Schmelzwärme hinein. Über einen Regeltransformator H wird an die Elektrode eine Wechselspannung,angelegt.In Figure 1, the hairpin-shaped electrode 11 is water-cooled Holders 12, which also serve to supply power, are held in the wall 13 of the heat of fusion and are sufficient into the interior of the heat of fusion. Via a regulating transformer H an alternating voltage is applied to the electrode.
In Figur 2 ist die Anordnung mehrerer haarnadelförmiger Elektroden in der Schmelzwanne schematisch dargestellt. Mit 21 bis 2jS sind die Elektroden bezeichnet, die in der Sehmelzwanne rechenförmig angeordnet sind, um einen geringen Elektrodenabstand zu erhalten.In Figure 2 is the arrangement of several hairpin-shaped electrodes shown schematically in the melting tank. With 21 to 2jS the electrodes are referred to, which are in the shape of a rake in the Sehmel tank are arranged in order to obtain a small electrode spacing.
Beim Anheizen wird zunächst durch jede dieser haarnadelförmigen Elektroden ein so großer Strom geschickt, daß durch die Stromwärme, die sich in den Elektroden entwickelt, das umgebende Schmelzgut schmilzt und soweit erhitzt wird, daß ein Stromdurchgang zwischen den einzelnen Elektroden erfolgen kann. Danach werden die Elektroden 21, 23 und 25 sowie 22, 24 und 26 parallel geschaltet; der weitere Schmelzprozeß erfolgt dann in an sich bekannter Weise.When heating up, each of these is initially hairpin-shaped Electrodes sent such a large current that the heat of the current that develops in the electrodes affects the surrounding melting material melts and is heated to such an extent that current can pass between the individual electrodes. After that, the Electrodes 21, 23 and 25 as well as 22, 24 and 26 connected in parallel; the further melting process then takes place in a manner known per se.
Die Vorrichtung gemäß der !feuerung eignet sich insbesondere zum Herstellen von hochschmelzenden Gläsern, z.B. G-rundgläsern für gesteuerte Entglasung.The device according to the fire is particularly suitable for the production of high-melting glasses, e.g. G-round glasses for controlled devitrification.
