Abstract

The invention relates to the technical field of copper wire processing and particularly discloses a processing technology for producing tinned copper wires by utilizing waste copper wires and a soaking and cleaning device. The processing technology of the tinned copper wires comprises the steps of copper wire preparation, low-temperature annealing, mixed blank wiredrawing, crystallization annealing, surface roughening and surface tinning to obtain the tinned copper wires. The copper wire preparation step comprises the following specific steps that to-be-treated recycled copper waste is sequentially subjected to crushing, vibration separation, electrostatic separation and magnetic separation to obtain recycled copper particles; the recycled copper particles are subjected to acid pickling, cleaning liquid washing, water washing and vacuum freeze drying to obtain a pretreated recycled copper material; and a copper material and the recycled copper material are molten and mixed to obtain amixed blank. According to the processing technology of the tinned copper wires, the recycled copper waste is treated and subjected to melting and mixing with the copper material to form the mixed blank, so that the recycled copper waste is utilized, the tinned copper wires are enabled to have good corrosion resistance and oxidation resistance, and the service life is prolonged.

Description

technical field [0001] The application relates to the technical field of copper wire processing, more specifically, it relates to a processing technology for producing tinned copper wire by using waste copper wire and a soaking and cleaning device. Background technique [0002] Copper is a kind of soft metal. Because copper has the advantages of good ductility, thermal conductivity and electrical conductivity, it is widely used in cables, electrical and electronic components. Among them, the general step of copper wire in the related art is copper wire Material preparation, low temperature annealing, copper wire drawing, recrystallization annealing, etc. As the use of copper wires continues to increase, a large amount of waste copper wires will also be produced. In related technologies, the waste copper wires are generally pickled, then re-smelted, and made into copper wires, so as to realize the recycling of waste copper wires. use. [0003] In view of the above-mentioned...
