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...

Abstract

The invention discloses an alloy copper pipe annealing device and an alloy copper pipe annealing treatment method. The alloy copper pipe annealing device comprises an annealing furnace, a stacking machine, an annealing material rack, a vacuumizing device, a nitrogen supply device and a PLC control system, a conveying roller way and a heating device are installed in the annealing furnace, the annealing material rack moves along the conveying roller way, a plurality of containing positions with nitrogen pipelines are arranged on the annealing material rack, a plurality of heating stations are arranged in the heating area, heating area purging rods are arranged on the heating stations, air inlets of the heating area purging rods are connected with the nitrogen supply device, air outlets of the heating area purging rods are opposite to the nitrogen pipelines, and electric contact pressure gauges are installed on the heating area purging rods. According to the annealing treatment method, inthe annealing process, the electric contact pressure gauges are used for detecting the air pressure in a coiled copper pipe, the inner purging fault problem is reflected and found in time, the process defects that the inner surface of the annealed coiled copper pipe becomes black due to inner purging failure and the like are overcome, the structure is simple, and detection is convenient and effective.
