When the air pressure is too high (the air pressure of the inner cavity 3 will increase when the heating component 4 is heated), the pressure relief valve 7 is activated to release the pressure of the inner cavity 3 to ensure the safety of the inner cavity 3.

[0024] It also includes a control device 8, which is electrically connected to the heating component 4.

[0025] A mounting frame 9 is provided on the cover body 2, and the cover body 2 is mounted on the sling through the mounting frame 9; the sling can drive the cover body 2 to move horizontally and up and down; when the workpiece is annealed, the sling drives the cover body 2 to move above the outer cylinder 1, and then drives the cover body 2 to move downward so that the cover body 2 covers the top opening of the inner cavity 3; when the annealing process is completed, the sling drives the cover body 2 to move upward, and then removes the cover body 2.

[0026] The cover body 2 includes a covering plate 10 and a closing piece 11 arranged at the bottom of the covering plate 10. A supporting edge 12 is arranged at the top opening of the inner cavity 3.
