specific Embodiment approach 1

[0032] Specific implementation mode one: combine figure 1 Describe this embodiment, the specific steps of the method described in this embodiment are as follows:

[0033] Step 1. Machining waste copper-clad aluminum wires and waste copper wires:

[0034] Firstly, the recovered waste copper-clad aluminum wires and waste copper wires are bundled into bundles, and then the bundled waste copper-clad aluminum wires and waste copper wires are processed into waste copper-clad aluminum wires and waste copper-clad aluminum wires with a length of 0.5-1.0mm by using a pulverizer. Copper wire particles;

[0035] Step 2, assembly and feeding of extrusion die 1:

[0036] First assemble the extrusion die 1 and put the processed waste copper-clad aluminum wire and waste copper wire particles into the extrusion cylinder inner sleeve 1-1 of the extrusion die 1, and then insert the thermocouple into the extrusion cylinder inner sleeve 1-1 scrap copper clad aluminum wire and scrap copper wire ...

specific Embodiment approach 2

[0054] Specific implementation mode two: combination figure 1 To illustrate this implementation mode, the scrap copper wire described in step 1 in this implementation mode is a pure copper wire. Other method steps are the same as those in the first embodiment.

Abstract

The invention relates to a method for regenerating aluminium-copper intermediate alloy by extruding the waste copper-clad aluminium conductor and the waste copper conductor for three times, belonging to the method for regenerating alloy, and aiming to solve the problems that the existing method for recovering the waste copper-clad aluminium conductor can not be used on a large scale, serious pollution is caused during recovering, more energy is consumed and the finished product from recovery can not be used directly. The method comprises the following steps: (1) mechanically processing the waste copper-clad aluminium conductor and the waste copper conductor; (2) assembling an extruding mold 1 and charging; (3) heating the extruding mold 1; (4) extruding for the first time; (5) mechanically processing the alloy rod obtained by extruding for the first time; (6) heating for the first time; (7) extruding for the second time; (8) mechanically processing the alloy rod obtained by extruding for the second time; (9) heating for the third time; and (10) extruding for the third time. The method is convenient to operate, is reasonable in design, discharges less carbon, is environmentally frienly and is used for regenerating the aluminium-copper intermediate alloy from the waste copper-clad aluminium conductor and the waste copper conductor.

Description

technical field [0001] The invention relates to a method for regenerating alloys, in particular to a method for regenerating aluminum-copper intermediate alloys by extruding waste copper-clad aluminum wires and waste copper wires three times. Background technique [0002] At present, there are two main methods of recycling waste copper-clad aluminum wires in China: one is to soak waste copper-clad aluminum wires in sulfuric acid and hydrogen peroxide to obtain copper salt solution and aluminum wire; the other is to use CuSO 4 ·5H 2 O and H 2 SO 4 As the electrolyte, the copper-clad aluminum wire is electrolyzed to obtain aluminum on the anode and copper on the cathode. Most of the existing recycling methods use acid as the recycling medium, and a large amount of sewage and chemical waste will be generated during the recycling process, which has caused serious damage and pollution to the natural environment and people's living environment. Due to the use of a large amount...
