Abstract
Description
Die Erfindung betrifft ein Kathodenblech für die elektrolytische Zinkgewinnung.The The invention relates to a cathode plate for electrolytic zinc extraction.
Der EP-B 0 454 056 ist ein Kathodenblech aus Aluminium für die elektrolytische Gewinnung von Zink zu entnehmen, mit einer Platte aus Aluminium und einer auf mindestens einem Rand der Platte, diesen umgebend, aufgebrachten Isolationsleiste aus Kunststoff.Of the EP-B 0 454 056 is a cathode plate made of aluminum for the electrolytic Extraction of zinc, with a plate of aluminum and one on at least one edge of the plate, surrounding it, applied Insulation strip made of plastic.
Die für die Zinkelektrolyse verwendeten Kathodenbleche bestehen in der Regel aus Aluminium und benötigen für den elektrischen Anschluss Kupfer in einer elektrisch leitenden Verbindung. Diese Kontakte sind durch die aggressiven Umgebungsbedingungen in der Elektrolyse einem starken Verschleiß durch Korrosion und Erosion ausgesetzt.The for the Zinc electrolysis used cathode sheets are usually made of aluminum and need for the electrical connection copper in an electrically conductive connection. These contacts are due to the harsh environmental conditions in the electrolysis a strong wear by corrosion and erosion exposed.

Ziel
des Erfindungsgegenstandes ist es, ein Kathodenblech für die elektrolytische
Zinkgewinnung dahingehend weiterzubilden, dass einerseits eine erhöhte Lebensdauer
und andererseits ein geringerer elektrischer Übergangswiderstand im Einsatz
in der Zinkelektrolyse gegeben ist. Zu diesem Zweck soll ein gegenüber der
Dieses Ziel wird erreicht durch ein Kathodenblech für die elektrolytische Zinkgewinnung, beinhaltend eine aus Aluminium bzw. einer Aluminiumlegierung bestehende Tragstange, die mit einem Kontaktelement in Wirkverbindung steht, wobei das Kontaktelement einen Grundkörper aus Aluminium bzw. einer Aluminiumlegierung beinhaltet, der außenseitig über einen vorgebbaren Bereich mit einer Schicht aus Kupfer bzw. einer Kupferlegierung versehen ist und die Verbindung zwischen dem Grundkörper und der Schicht durch einen Warmumformprozess herbeigeführt ist.This Goal is achieved by a cathode plate for electrolytic zinc production, including one made of aluminum or an aluminum alloy Support rod, which is in operative connection with a contact element, wherein the contact element is a base body made of aluminum or a Aluminum alloy includes, the outside over a predeterminable area provided with a layer of copper or a copper alloy is and the connection between the body and the layer through a hot forming process is brought about.
Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.advantageous Further developments of the subject invention are the dependent claims remove.
Der aus Aluminium bzw. einer Aluminiumlegierung bestehende Grundkörper ist vorteilhafterweise etwa plattenartig ausgebildet, wobei die Schicht einen etwa U- förmigen Querschnitt aufweist und die zugehörigen Wandbereiche des Grundkörpers zumindest partiell umschließt.Of the made of aluminum or an aluminum alloy existing body is advantageously formed approximately plate-like, wherein the layer has a approximately U-shaped cross-section has and the associated Wall areas of the body at least partially encloses.
Je nach Ausführung kann es sinnvoll sein, den Grundkörper über seine gesamte Höhe mit der aus Kupfer bzw. einer Kupferlegierung bestehenden Schicht zu versehen. Durch diese Maßnahme wird sichergestellt, dass eine große Berührungsfläche zwischen dem Grundkörper und der Schicht erzeugt wird. Diese vergrößerte Verbindungsfläche ist für eine längere Standzeit des Kontakts und damit des Kathodenbleches und einen geringeren elektrischen Übergangswiderstand im Einsatz verantwortlich.ever after execution It may be useful to extend the body over its entire height with the Copper or a copper alloy existing layer to provide. By this measure Ensures that a large contact surface between the body and the layer is generated. This enlarged connection surface is for one longer Service life of the contact and thus the cathode plate and a lower electrical contact resistance responsible in action.
Vorteilhafterweise wird die primäre Verbindung zwischen der Kupferschicht und dem Aluminium-Grundkörper durch einen Warmumformprozess erzeugt. Der sekundäre Verbund des Kupfer-Aluminium-Grundkörpers mit der Tragstange erfolgt, einem weiteren Gedanken der Erfindung gemäß, durch Schweißen.advantageously, becomes the primary one Connection between the copper layer and the aluminum base by produces a hot forming process. The secondary bond of the copper-aluminum basic body with the support rod is, according to another idea of the invention, by welding.
Der Erfindungsgegenstand ist anhand eines Ausführungsbeispiels in der Zeichnung dargestellt und wird wie folgt beschrieben:Of the Subject of the invention is based on an embodiment in the drawing and is described as follows:
