[0029] It should be noted that, by providing the anti-slip part 15, it is easier to transport the molybdenum wire. By providing the through hole 2, the molybdenum wire can be delivered to the fixed cylinder 9 inside the annealing box 1 and then transmitted out from the through hole 2 at the other end. By providing the air inlet 4, nitrogen or helium can be delivered to the inside of the annealing box 1 to reduce oxidation of the molybdenum wire during annealing. By providing the first notch 10 and the second notch 11, the molybdenum wire can be briefly cooled at the position of the first notch 10 and the second notch 11, and then the next annealing can be carried out, so that the continuous annealing of the molybdenum wire is more uniform.
