[0002] Before coating the surface of the aluminum alloy wheel of the automobile, it is necessary to preheat the aluminum alloy wheel of the automobile to improve the coating effect. The existing preheating method is completed by electric heating. Several fixed electric heating plates are placed above the serpentine conveyor rail, and the heat generated by the electric heating plates is used to preheat the aluminum alloy wheels of the automobile. When this preheating method is used, due to the short heating time and uneven heating Therefore, the heating effect is not good, which affects the subsequent coating quality. Moreover, this heating method consumes a lot of energy and costs high
