Description

Nach dem Patent No. 47031 verwendet man bei der Darstellung von Aluminium Gefäfse mit gekühlten Wandungen, zu dem Zwecke, an diesen Wandungen die flüssige Reactionsmasse ganz oder theilweise zu einer schützenden Kruste erstarren zu lassen und so die Wandungen vor Zerstörung durch die schmelzenden Materialien und durch das erzeugte flüssige Aluminiummetall und letzteres vor Verunreinigung durch die Masse der Gefäfswandungen zu bewahren.According to the patent no. 47031 is used in the representation of aluminum vessels with cooled walls, for the purpose of on these walls the liquid reaction mass becomes wholly or partly a protective one To solidify the crust and so protect the walls from being destroyed by the melting Materials and by the generated liquid aluminum metal and the latter from contamination to be preserved by the bulk of the vessel walls.

Eine solche Anwendung von Gefäfsen mit gekühlten Wandungen ermöglicht eine ununterbrochene Darstellung im Grofsen und die Ausführung der Reductionsoperationen in ein und demselben Reductionsgefäfs unmittelbar oder in kurzen Zeitzwischenräumen hinter einander. Such an application of vessels with cooled walls enables uninterrupted Representation on a large scale and the execution of the reduction operations in one and the same reduction vessel immediately or in short intervals of time one after the other.

Liegen zwischen den einzelnen Reductionsoperationen gröfsere Zeitzwischenräume, so dafs nach jeder einzelnen Reduction eine genügende Abkühlung des Gefäfses eintritt', indem man z. B. für eine bestimmte Anzahl von Reductionen eine gleiche Anzahl von Reductionsgefäfsen anwendet, oder wenn überhaupt nur beabsichtigt wird, eine einzige Reaction in dem Gefäfs vorzunehmen, so kann man der künstlichen Kühlung besonders während der Operation entbehren, da alsdann die Gefäfswände selbst die zur Krustenbildung nothwendige Abkühlung der Reactionsschmelze zu bewirken im Stande sind.If there are longer periods of time between the individual reduction operations, see that after each individual reduction there is sufficient cooling of the vessel by one z. B. for a certain number of reductions an equal number of reduction vessels uses, or if it is intended at all, a single reaction to be carried out in the vessel, one can use the artificial cooling especially during The operation is unnecessary, since then the vessel walls themselves are responsible for the formation of crusts are able to bring about the necessary cooling of the reaction melt.

Falls man es für zweckmäfsig erachten sollte, kann man die Gefäfse vor ihrer Verwendung schon mit gepulvertem Kryolith oder mit Thonerde, Magnesia oder sonstigen siliciumfreien, von Aluminium unangreifbarenMaterialen, etwa durch Ausstampfen mit solchen gepulverten Stoffen, ausfüttern.If it is deemed appropriate, the vessels can be removed before they are used already with powdered cryolite or with alumina, magnesia or other silicon-free, materials that cannot be attacked by aluminum, e.g. by stamping them with powder Fabrics, lining.

Durch solche Anwendung kalter, d. h. ungeheizter Reductionsgefäfse erreicht man ebenfalls, wie in dem Patent No. 47031 beschrieben, dafs die kalten bezw. ungeheizten Gefäfswandungen (mögen dieselben ausgefüttert sein oder nicht) durch Abkühlung der Schmelze und durch so bewirktes völliges oder theilweises Erstarren der letzteren sich mit einer vor den Einwirkungen des übrigen Theiles der Schmelze oder des geschmolzenen Aluminiummetalles schützenden Kruste überziehen und so gewissermafsen vor der directen Berührung mit der flüssigen Schmelze oder dem flüssigen Aluminiummetall geschützt wird. λ By using cold, ie unheated, reduction vessels in this way, one also achieves, as in patent no. 47031 described that the cold resp. Unheated vessel walls (whether they are lined or not) by cooling the melt and thus causing the latter to solidify completely or partially, are covered with a crust protecting against the effects of the remaining part of the melt or the molten aluminum metal and so to a certain extent against direct contact with it the liquid melt or the liquid aluminum metal is protected. λ

Es ist selbstverständlich, dafs die kühlende Kraft der Gefäfswandungen eine um so gröfsere ist, je stärker dieselben entweder an sich oder durch irgend' welche Verkleidung sind.It goes without saying that the cooling power of the vessel walls is all the greater is, the stronger they are either in themselves or through some disguise.

Patεnt-Anspruch:Patent claim:

Das durch Patent No. 47031 geschützte Verfahren zur Gewinnung von Aluminium mit der Abänderung, dafs man in diesem Verfahren ah Stelle der in Theil c) des Haupt-Anspruches bezeichneten Gefäfse mit gekühlten Wandungen kalte bezw. ungeheizte Gefäfse in Verbindung mit den unter a) und b) unverändert bleibenden Operationen anwendet.The patent no. 47031 protected process for the extraction of aluminum with the modification that in this procedure one should replace that in part c) of the main claim designated vessels with cooled walls cold respectively. unheated vessels in connection with the operations that remain unchanged under a) and b).
