[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0019] As Figures 1 to 5 shown, the flange annealing tool comprises a hoisting assembly 1 and an annealing box 2, the annealing box 2 is arranged at the lower end of the hoisting assembly 1, when the hoisting assembly 1 is placed on the annealing box 2, the hoisting assembly 1 is pushed downward, the annealing box 2 is kept clamped on the hoisting assembly 1, so that the hoisting assembly 1 can be moved to a specified position for annealing treatment.

[0020] The hoisting assembly 1 is provided with a hoisting piece 3 and a hoisting seat 4, the hoisting piece 3 is provided with symmetrical lifting rings 5, the lifting rings 5 facilitate hoisting of the hoisting assembly 1, and a plurality of lifting rings 5 can be arranged according to actual needs to ensure stability of the hoisting assembly 1.
