Problems solved by technology
However, in the existing copper wire production process, after the copper wire passes through the condensed water, it is necessary to use a large-power wind pound to blow the water on the surface of the copper wire. However, due to the small diameter of the copper wire and the fast passing speed, Air-dried copper wire surface moisture effect is poor

Embodiment Construction
[0023] refer to Figure 1 to Figure 2 , the present invention is implemented like this:
[0024] exist figure 1 Among them, a copper wire production process that reduces oxidation, its steps are:
[0025] 1) Pass the copper rod through the wire drawing process (1) to form fine copper wires;
[0026] 2) the copper wire is annealed and softened (2) processing;
[0027] 3) The copper wire (10) after the annealing and softening process (2) of the high-temperature vacuum annealing tube is subjected to the cooling process (3) with the condensed water in the condensed water tank (30), and timely cooling prevents the copper wire (10) from Oxygen in the air is oxidized at high temperature;
[0028] 4) performing the air-drying process (4) on the copper wire (10) after the cooling process (3) to obtain the final copper wire product;
[0029] Wherein the pH value of condensed water in step 3) is 7.0-7.1, and the air-drying procedure (4) in step 4) is as follows: first will pass thro...

The invention relates to a brass wire production process, in particular relates to a brass wire production process for reducing oxidation, comprising the following steps: 1) a brass bar is made into fine brass wires after a wire drawing process; 2) annealing softening processing is carried out on the brass wires; 3) the brass wires are annealed by a vacuum annealing pipe with high temperature andthen cooled by condensing water in a condensing water tank, and timely cooling can prevent the brass wires from being oxidized by oxygen in high temperature air; 4) an air drying process is carried out on the cooled brass wires to obtain final brass wire products; the pH value of the condensing water in the step 3 is 7.0-7.1. In the air drying process of the step 4, a group of wind pounds is usedfor blowing and drying the brass wires which penetrate out of the condensing water dry, and then the brass wires penetrate a clean water-absorbing felt group. The brass wire production process has the advantages of greatly improving the anti-oxidization ability of the brass wires which are produced according to the process, saving the wind pounds, lowering the electricity utilization cost and lowering the blowing noises of the wind pounds.
Description
technical field [0001] The invention relates to a copper wire production process, in particular to a copper wire production process for reducing oxidation. Background technique [0002] Generally, copper rods with a diameter of more than 2.6mm need to go through several sets of processes such as large drawing, medium drawing, and small drawing before forming fine copper wires. First, the copper wire is processed in the annealing and softening process. After the annealing and softening process, the copper wire will undergo oxidation reaction. After the copper wire is continuously annealed through the high-temperature vacuum annealing tube, it is immediately cooled in condensed water with a pH value of 7.0-7.1. Prevent the oxidation of copper wire and oxygen in the air at high temperature, and the removal of moisture on the surface of the copper wire after the copper wire passes through the condensed water also affects the oxidation of the copper wire. However, in the existin...
