Example Embodiment
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] Embodiments of the present invention: when implementing the present invention, firstly, a thermal insulation and anti-oxidation covering device for thermal insulation and oxidation prevention during production of an aluminum electrolytic cell of the present invention is produced. The schematic structural diagram of the device is as follows: figure 1 and figure 2 As shown, the device is composed of a steel member plate 1 and a heat-insulating refractory block 2 connected. The steel member plate 1 can be made of ordinary steel plates, and the heat-insulating refractory block 2 can be made of existing materials with corrosion resistance and fire resistance. When the heat preservation and refractory material block 2 is made into a whole with the steel member plate 1 through the bolts 3; the steel member plate 1 and the heat preservation an...
