Example Embodiment
[0024] The specific content of the present invention will be described in detail below with reference to the drawings and specific embodiments.
[0025] Such as figure 2 As shown, a copper wire drawing annealing method is characterized in that it comprises the following steps:
[0026] S1. Blow nitrogen to remove air,
[0027] Such as figure 1 As shown, the nitrogen gas storage tank 1 and the dryer 2, the flow meter 4, the on-off valve 5, and the annealing chamber 9 are connected in sequence through the connecting pipe 6. After the nitrogen is dried by the dryer 2, the air pressure is displayed in real time by the flow meter 4, and the valve is switched on and off. 5 Control the switch of nitrogen, and finally enter the sealed tube 10 of the annealing chamber 9;
[0028] S2. The copper wire enters the annealing chamber 9 and is heated,
[0029] Fill the sealed tube 10 with nitrogen, then pass the copper wire through the sealed tube 10, pass the copper wire through the sealed tube 10 ...
