Description

Die Erfindung bezieht sich auf Kathoden und insbesondere auf Kathoden für die Verwendung bei der elektrischen Gewinnung oder Raffination von Kupfer.The invention relates to cathodes and, more particularly, to cathodes for use in the electrical extraction or refining of copper.

Die DE-PA 25 50 178.4 betrifft eine Zusammenstellung aus Kathode und Hängeschiene, die dadurch gekennzeichnet ist, daß sie aus einer Hängeschiene aus Aluminium oder Kupfer mit einem Kern aus einem damit metallurgisch verbundenen filmbildenden Material, wobei Aluminium oder Kupfer entlang der Länge der Hängeschiene abgenommen ist, um das filmbildende Metall freizulegen, und aus einer durchgehenden Platte eines filmbildenden Metalls besteht, die entlang nur eines Rands an mindestens einem Teil des Kerns aus filmbildendem Metall angeschweißt ist.DE-PA 25 50 178.4 relates to a combination of cathode and hanging rail, which is characterized in that it consists of a hanging rail made of aluminum or copper with a core made of a metallurgically bonded film-forming material, aluminum or copper being removed along the length of the hanging rail to expose the film-forming metal and consists of a continuous sheet of film-forming metal welded along only one edge to at least a portion of the core of film-forming metal.

Es hat sich nunmehr herausgestellt, daß die Platte aus filmbildendem Metall durch eine Platte aus rostfreiem Stahl, rostfreiem Eisen oder einer anderen korrosionsbeständigen Eisenlegierung bestehen kann. Bei einer solchen Anordnung muß der Kern nicht aus einem filmbildenden Metall bestehen, sondern es kann für den Kern jedes andere geeignete Metall, wie z.B. Flußstahl, rostfreier Stahl oder Eisen verwendet werden.It has now been found that the plate of film-forming metal can consist of a plate of stainless steel, rust-proof iron or some other corrosion-resistant iron alloy. In such an arrangement, the core need not be made of a film-forming metal, any other suitable metal, such as mild steel, stainless steel, or iron, can be used for the core.

So betrifft also die vorliegende Erfindung eine Abwandlung der Erfindung der DE-PA 25 50 178.4, die dadurch gekennzeichnet ist, daß der Kern aus einem anderen Metall als Aluminium oder Kupfer besteht und daß die durchgehende Metallplatte, die entlang nur eines Rands an mindestens einem Teil des Kerns angeschweißt ist, aus rostfreiem Stahl, rostfreiem Eisen oder einer anderen korrosionsbeständigen Eisenlegierung besteht.So the present invention relates to a modification of the invention of DE-PA 25 50 178.4, which is characterized in that the core consists of a metal other than aluminum or copper and that the continuous metal plate, which runs along only one edge on at least one part welded to the core, made of stainless steel, stainless iron or another corrosion-resistant iron alloy.

Beispielsweise kann die durchgehende Metallplatte aus einem säurebeständigen rostfreien Stahl AISI (American Iron and Steel Institute) 316 oder 316L bestehen, das ist eine Legierung, die 17 % Chrom, 12 % Nickel, 2 1/2 % Molybdän, weniger als 0,08 % Kohlenstoff und im übrigen Eisen enthält.For example, the continuous metal plate can consist of an acid-resistant stainless steel AISI (American Iron and Steel Institute) 316 or 316L, that is an alloy that contains 17% chromium, 12% nickel, 2 1/2% molybdenum, less than 0.08% Contains carbon and otherwise iron.

1. Abwandlung der Zusammenstellung aus Kathode und Hängeschiene gemäß DE-PA 25 50 178.4, dadurch gekennzeichnet, daß der Kern aus einem anderen Metall als Aluminium oder Kupfer besteht und daß die durchgehende Metallplatte, die entlang nur eines Rands an mindestens einem Teil des Kerns angeschweißt ist, aus rostfreiem Stahl, rostfreiem Eisen oder einer anderen korrosionsbeständigen Eisenlegierung besteht.1. Modification of the combination of cathode and hanging rail according to DE-PA 25 50 178.4, characterized in that the core consists of a metal other than aluminum or copper and that the continuous metal plate, which is welded along only one edge to at least part of the core is made of stainless steel, stainless iron or another corrosion-resistant iron alloy. 2. Zusammenstellung nach Anspruch 1, dadurch gekennzeichnet, daß die durchgehende Metallplatte aus einer Legierung besteht, die 17 % Chrom, 12 % Nickel, 2 1/2 % Molybdän und im übrigen Eisen enthält.2. Composition according to claim 1, characterized in that the continuous metal plate consists of an alloy which contains 17% chromium, 12% nickel, 2 1/2% molybdenum and the rest of iron.
