The first end of the annealing tube 11 is located below, and the second end is located above the first end. The wire 3 passes into the annealing tube 11 from the first sealing member 111 and passes out of the second sealing member 112. The high temperature in the annealing furnace 1 heats the annealing tube 11, so that the water in the annealing tube 11 and the wire 3 are heated at the same time. The wire 3 is annealed during the heating process, and the water generates steam during the heating process. The steam fills the annealing tube 11 to provide steam protection for the heated wire 3.

[0031] Optionally, the first sealing member 111 is provided with a sliding sealing hole. The annealing wire 3 passes through the sliding sealing hole and is in sealing contact with the first sealing member 111. The first sealing member 111 seals the first end of the annealing tube 11 to prevent the water in the annealing tube 11 from flowing out. The second sealing member 112 is provided with a sliding hole. The annealing wire 3 passes out of the sliding hole and is in contact with the second sealing member 112. The second sealing member 112 makes the second end of the annealing tube 11 in a semi-sealed state, so that a certain amount of steam can be maintained in the annealing tube 11, and a small amount of steam can flow out through the sliding hole to avoid excessive pressure in the annealing tube 11.

The water tank 2 is in a closed state, and deionized water is stored in the water tank 2.
