The aluminum alloy heat preservation furnace 1 includes a heat preservation furnace body 11. A control panel 12 is fixedly installed on the front of the heat preservation furnace body 11. A sealing frame 13 is fixedly installed on the inner wall of the control panel 12. A support component 2 is provided inside the aluminum alloy heat preservation furnace 1. A protective component 3 is provided on the top of the aluminum alloy heat preservation furnace 1. An electric heater 4 is provided on the surface of the protective component 3. The protective component 3 includes a protective unit and a heat dissipation unit. The protective unit includes a sealing cover 31, a protective cover 32 and an inspection door 33. The vertical structure ensures uniform heat transfer, and the gas flows from bottom to top to optimize heat distribution and enhance reaction efficiency. It is suitable for high-temperature processing such as pyrolysis and sintering.

[0028] Example 2

[0029] like Figures 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the support component 2 includes a support rod 21 fixedly installed on the surface of the sealing frame 13, a mounting plate 22 fixedly installed at one end of the support rod 21, a clamping ball 23 slidably installed inside the mounting plate 22, a sealing cover 31 installed on the top of the heat preservation furnace body 11 by screws and the sealing frame 13, a bottom surface of the protective cover 32 and a top surface of the sealing cover 31 fixedly connected, an inspection door 33 installed on the top of the protective cover 32 by a hinge, and a heat dissipation unit including a ventilation hole 34 provided on the left side of the protective cover 32, a filter cover 35 fixedly installed on the right side of the protective cover 32, and a cooling fan 36 fixedly installed inside the filter cover 35.
