The induction heating assembly 1 can be installed above the support frame 4, the induction heating assembly 1 is installed on the first side of the support 2, the induction heating assembly 1 comprises a box 11, in this embodiment, two induction heating coils 12 are arranged in the box 11, and the two induction heating coils 12 are arranged in the box 11 along the length direction of the box 11. The induction heating coils 12 can be arranged in a plurality according to actual needs, and the specifications of the induction heating coils 12 can be determined according to the properties of the wire, for example, the properties of the wire include but are not limited to diameter, material, temperature requirements and other performance indicators.

[0034] When heating the wire, the wire is first quickly heated by the induction heating component 1, and then enters the heating furnace pipe 3 for heat preservation heating to eliminate the skin effect on the surface of the wire to achieve uniform heating, and finally complete the heating treatment. The utility model combines resistance heating and induction heating well, and reasonably exerts the advantages of the two heating modes. Compared with only using the resistance heating mode, it is not necessary to design the heating furnace to be very long, thereby avoiding the problems of wire sagging and scratching the furnace tube, inconvenient maintenance, etc. Compared with only using the induction heating mode, the heating furnace can eliminate the skin effect caused by induction heating while ensuring rapid heating. The surface of the wire is heated evenly, the heating speed is greatly improved, and the heating effect is also guaranteed, which is very practical.
