Embodiment 2

[0039] Such as figure 1 As shown, what this embodiment provides is a method for annealing an alloy copper tube, which is characterized in that it includes the following steps:

[0040] A. Stacking: The stacker stacks a number of coiled copper tubes to be annealed and places them on the storage position of the annealing rack, and makes the tube head of each coiled copper tube dock with the gas outlet of the nitrogen pipeline ;

[0041] B. Gas replacement: the annealing material rack equipped with coiled copper tubes to be annealed enters the vacuum chamber of the annealing furnace, and the vacuuming device performs vacuuming action on the vacuum chamber, and the air is exhausted until the vacuum degree in the vacuum chamber reaches the first preset air pressure , the nitrogen supply device backfills the vacuum chamber with nitrogen until the nitrogen in the vacuum chamber reaches the second preset pressure to complete the gas replacement action;

[0042] In this embodiment, t...
