[0033] The inner coil 16 is a tightly wound copper pipe, the outer coil 17 is a sparsely wound copper pipe, and the distance between the two layers is five centimeters. The inner coil 16 is responsible for high-frequency shallow heating, and the outer coil 17 realizes medium-frequency deep heat penetration. The phase difference of the current transmitted by the controller 12 forms a superimposed magnetic field;

[0034] When the device is in use, the top cover 3 can be opened, and then the hub is put into from the upper end. As the depth of the hub, the position sensor 14 will sense the entry of the object, and command the rear-end control system to open the corresponding height controller 12. Then the inner coil 16 and the outer coil 17 will be energized, and then the corresponding height magnetic field is formed, realizing the heating and heat preservation effect on the surface of the hub. If the temperature of the heating is too high, the control valve 21 of the built-in temperature control system will be opened, and the heat will be transmitted from the inner area of the fixed frame 15 in the box body 1 to the interlayer 19 through the transmission pipe 22, and at the same time the water tank 9 will continuously supply water to the inside of the protective layer 20 by using the built-in water pump, realizing the effect of water cooling, so that the gas transmitted to the inside of the interlayer 19 in the fixed frame 15 is cooled, so as to realize the heat preservation effect of the hub in the fixed frame 15, preventing the temperature from being too high or too low to affect the physical and chemical properties of the hub surface.
