[0052] The use process of the furnace electric heating device provided by the utility model is as follows:

In cooperation with the limit rod 505, the second bevel gear 503 can drive the threaded rod 504 to rotate. As the threaded rod 504 rotates, due to the opposite directions of the threads at both ends of the threaded rod 504, the two T-shaped rods 506 move in opposite directions, thereby causing the two connecting plates 507 to move, and the connecting plate 507 drives the connecting rod 602 to move, so that the sealing plate 301 moves, and the sealing plate 301 drives the arc heater 2 to move out of the furnace body 1. In cooperation with the external fan, the arc heater 2 can achieve rapid heat dissipation. After the heat dissipation is completed, the stepper motor 501 is controlled to work, and the output shaft of the stepper motor 501 rotates in the opposite direction, so that the arc heater 2 moves into the furnace body 1, the sealing plate 301 moves into the slot, the high temperature resistant rubber layer 302 squeezes the furnace body 1, and the spring 603 is compressed to achieve the sealing between the sealing plate 301 and the furnace body 1. When heating is needed, the arc heater 2 works, and the stepper motor 501 is controlled to work at the same time, so that the connecting rod 602 drives the limiting column 601 to continue to move until the rack 605 is meshed with the gear 403, and the rack 605 continues to move, so that the gear 403 drives the rotating shaft 402 to rotate, and the spring 603 is further compressed, and the rotating shaft 402 drives the connecting block 404 to rotate, and the connecting block 404 drives the arc heater 2 to rotate a certain angle, and then the output shaft of the stepper motor 501 is controlled to rotate in the opposite direction, and the limiting column 601 drives the rack 605 to move in the opposite direction, and cooperates with the gear 403 to reset the arc heater 2. At the same time, under the action of the elastic force of the spring 603, the sealing plate 301 and the furnace body 1 are always in a sealed state. Through this arrangement, multiple arc heaters 2 can be repeatedly swung during operation, thereby achieving uniform heating in the furnace body 1 and improving practicality.
