Description

Technical Field

[0001] This application relates to the field of electromagnetic induction heating, and more particularly to a heating system specifically for slabs. Background Technology

[0002] Electromagnetic induction heating equipment is widely used due to its fast heating speed and high energy conversion efficiency. Its working principle is that the alternating induced magnetic field generated by the induction heater acts on the conductive material to be heated, generating an induced current in the material. The thermal effect of the current heats the material.

[0003] Existing technology offers a transverse magnetic induction heating solution, which boasts advantages such as high heating power density and high conversion efficiency, thus gaining widespread application. This transverse magnetic induction heating technology refers to the generation of an electromagnetic induction magnetic field that transversely passes through the plane of the heated slab. However, this technology inherently suffers from uneven transverse temperature distribution, including a low-temperature zone in the center and two low-temperature zones symmetrically positioned around the longitudinal center of the slab near the edges. This negatively impacts the quality of downstream slab processing. Summary of the Invention

[0054] In this embodiment of the application, the moving component 40 includes: a driver, a main drive gear 41, an upper moving component 42, and a lower moving component 43. The main drive gear 41 is connected to the driver, the upper moving component 42, and the lower moving component 43, respectively. The upper moving component 42 is connected to the upper center moving block 113 of the center heating electrode pair 11 and the upper side moving block 123 of the side heating electrode pair 12 of the electromagnetic induction heating component 10. The lower moving component 43 is connected to the lower center moving block 114 of the center heating electrode pair 11 and the lower side moving block 124 of the side heating electrode pair 12.

[0055] Specifically, the control component 50 sends control commands to the driver, which drives the main drive gear 41 to rotate.

The right main drive gear, upper right driven gear, lower right driven gear, upper right transmission screw, and lower right transmission screw respectively form a right moving component that acts on the right side moving block and the right side heating electrode pair. Neither the left moving component nor the right moving component interacts with the center heating electrode pair.

6. The slab-specific heating system according to claim 5, characterized in that, It also includes an upper right drive rod, a lower right drive rod, an upper center drive screw, a lower center drive screw, a first electrically controlled end face clutch device, a second electrically controlled end face clutch device, a third peripheral electrically controlled clutch device, and a fourth peripheral electrically controlled clutch device. The upper and lower center moving blocks each have a central block screw hole penetrating through the central block. The upper center drive screw and the lower center drive screw are respectively screwed into the upper and lower center block screw holes. The first and second electrically controlled end face clutch devices are fixedly connected to the left ends of the upper right drive rod and the lower right drive rod, respectively. The upper right drive screw and the lower right drive screw are electrically controllable and switchable at their right ends. Both the upper right drive screw and the lower right drive screw are hollow screws with through holes, and are respectively called the upper right hollow drive screw and the lower right hollow drive screw. The upper right drive screw passes through the upper right drive screw, and the lower right drive screw passes through the lower right drive screw. The third peripheral electrically controllable clutch device and the fourth peripheral electrically controllable clutch device are respectively mounted and fixed on the upper right drive screw and the lower right drive screw, and the third peripheral electrically controllable clutch device and the fourth peripheral electrically controllable clutch device are electrically controllable and switchable at their inner circles.
