Embodiment Construction

[0009] The invention relates to a method of joining a core 2 having good electrical conductivity to a cladding 1 made of refined steel. When using this method, the core member 2 with good electrical conductivity such as a copper rod and the connecting element 3 are placed in the sheath 1 with poor electrical conductivity; Forms a metallurgical bond with the cladding 1 of refined steel. The connection element 3 is approximately as long as the core piece 2 . Generally speaking, the connecting element 3 is tin. The amount of connecting elements 3 depends on the size of the gap between the jacket 1 and the core 2 and the size of the connection surface between the core and the tube.

[0010] A jacket is a tubular member at least partially plugged at least at one end thereof, at least during heat treatment. Generally speaking, before inserting the core 2 and the connecting element 3 into the envelope 1, the opening at the first end of the envelope is closed, for example by weldin...

Abstract

A method for joining a highly electroconductive core element (2) to a jacket element (1) made of refined steel. In said method, the electroconductive core element (2), such as a copper bar, and the joining agent element (3) are inserted in the jacket element (1), and at least the juncture area of the elements to be joined is thermally treated, so that there is created a metallurgical joint between the electroconductive core element (2) and the refined-steel jacket element (1).

Description

technical field [0001] The present invention relates to a method of connecting tubing to a core. Background technique [0002] The method according to the invention is particularly suitable for the manufacture of suspension rods for electrodes, in particular permanent cathodes, for the electrolysis of metals. To conduct a large current to the plate, the material on the suspension rod should be a substance with high conductivity such as copper. Therefore, the structure of the suspension rod of the permanent cathode and the connection between the plate of the permanent cathode and the suspension rod become question. Acid-resistant steel has poor electrical conductivity and cannot be used as the sole material for suspension rods. International patent application WO 00 / 17419 describes several methods of manufacturing permanent cathode suspension rods. These methods are generally complex or require special equipment, or both. According to the methods of the prior art, these p...
