Abstract

The invention discloses a process for a specially-shaped electrolytic conductive material. The process comprises the following steps of: 1) by taking highly-pure cathode copper as a raw material, performing centrifugal vacuum up-drawing continuous-casting on an oxygen-free copper rod by using a traction unit; 2) processing the oxygen-free copper rod in the step 1) by using a continuous extrusion unit to form a blank of the specially-shaped electrolytic conductive material; 3) drawing and finishing the blank of the specially-shaped electrolytic conductive material by using a fully-automatic hydraulic drawing machine to form the specially-shaped electrolytic conductive material, wherein the blank is formed in the step 2); and 4) checking and packaging the specially-shaped electrolytic conductive material which is formed in the step 3). The invention provides the specially-shaped electrolytic conductive material which is high in production efficiency, high in yield, high in product quality and free from environmental pollution and can overcome the defects of the conventional production process.

Description

technical field [0001] The invention relates to a processing technology of a special-shaped conductive material for electrolysis, belonging to the technical field of non-ferrous metal processing. Background technique [0002] The production of electrolytic copper is carried out in an electrolytic cell. Under the action of a low-voltage, high-current DC electric field, the copper ions in the electrolyte will be continuously enriched on the cathode, thereby obtaining high-purity electrolytic copper. According to the principle of copper electrolysis, in the electrolysis process, increasing the current density is an effective way to obtain high-grade electrolytic copper. The copper conductive plate and bus plate are necessary conductive materials to establish a DC electric field. Their working principle is: use a conductive pure copper square tube 1' to place the cathode copper 2' in the copper electrolyte 3', and place the cathode copper 2' between the two cathode copper 2'. C...
