Description

Technical Field

[0001] The utility model relates to the technical field of material preheating, in particular to a material preheating device for an industrial electric furnace. Background Art

[0002] Industrial electric furnaces are equipment specially used for heating and melting metal materials, of which the preheating device is a key component. Preheating the raw materials through the preheating device can not only significantly improve the thermal efficiency of the electric furnace, reduce energy consumption, and shorten the time for the material to reach the target temperature, but also improve product quality. This is because preheating helps reduce the internal stress of the material and avoids the temperature unevenness that may occur during the heating process, thereby ensuring uniform heating and performance improvement of metal materials such as pipes during processing. Therefore, the material preheating device is indispensable for improving the overall efficiency and output quality of industrial electric furnaces.

[0003] Traditional industrial electric furnace material preheating devices usually adopt the induction heating principle, transmitting alternating current through one or more induction coils to generate a changing magnetic field. When metal materials are placed in these coils, the magnetic field will generate eddy currents inside the materials, and the flow of these currents is converted into heat energy, thereby preheating the materials. Due to the directness of the heating method, the energy efficiency is extremely high, which greatly reduces energy loss. However, the traditional industrial electric furnace material preheating device pipes pass directly through the coils, and the short time is not taken into account, which will lead to poor preheating effect. Therefore, an industrial electric furnace material preheating device is proposed to solve the above problems. Utility Model Content

[0033] By starting the motor 10, the rotating plate 12 is driven to start rotating. During the rotation of the rotating plate 12, it will drive the connecting plate 17 to move accordingly. The connecting plate 17 moves up and down on the slide rail 15 through the slider 16. At the same time, the sliding block 14 moves left and right on the slide rail 13 to cooperate with the movement of the connecting plate 17 and the rotating plate 12. When the hook plate 15 moves from the bottom to the top with the mobile frame 18, it will transfer the pipes on the hook plate 27. As the mobile frame 18 moves from top to bottom, the pipes will also be transferred forward. In this way, as the mobile frame 18 moves back and forth continuously, the pipes at the rear can be gradually moved forward to achieve intermittent movement of the pipes.

[0035] During the process of preheating the pipes, the operator must first place the pipes to be preheated at the entrance of the material box 20. The pipes slide along the transfer rack 23. At this time, the baffle 21 can effectively guide the pipes to the inside of the material box 20. Subsequently, the pipes are orderly arranged inside the material box 20 under the guidance of the guide plate 22. The limit plate 24 plays a blocking role in this process to prevent the pipes from sliding from the inside of the transfer rack 23. In addition, the limit rack 25 inside the box 1 can limit the pipes so that they are evenly arranged, avoiding the blockage problem caused by uneven arrangement of the pipes. The pipes will eventually stop inside the inclined plate 26, and the lowest pipe will stop above the hook plate 27, ensuring the stable parking of the pipes.

[0036] Working principle: When using the equipment to preheat pipes, first put the pipes to be preheated into the material box 20 through the baffle 21. The pipes will be arranged in the material box 20 through the guide plate 22, and slide along the transfer rack 23, and finally slide into the box body 1. The limit plate 24 has the effect of blocking the pipes to prevent the pipes from sliding from the inside of the transfer rack 23. The limit rack 25 inside the box body 1 will limit the pipes to arrange them evenly to avoid blockage. The pipes will eventually stop inside the inclined plate 26, and the lowest pipe will stop above the hook plate 27. At this time, the motor 10 is started to drive the rotating plate 12 to rotate, and the rotating plate 12 will bring The movable connecting plate 17 moves, and the connecting plate 17 moves up and down on the slide rail 2 15 through the slider 16. While moving up and down, the sliding block 14 moves left and right on the slide rail 13. When the hook plate 15 follows the moving frame 18 to move from bottom to top, the pipe on the hook plate 27 will be transferred, and the pipe will be transferred forward as it moves from top to bottom. With the reciprocating movement of the moving frame 18, the pipe at the rear is gradually moved forward. After the pipe enters the interior of the preheating frame 2, the induction heating wire 3 will heat it, and the heating temperature can be adjusted by the controller 29. The heated pipe will slide out of the interior of the box body 1 through the discharge rack 19.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
