Hot tank treatment:

1) The initial hot stroke of the electrolytic tank is not considered a disease tank. The treatment method is very simple. As long as the working voltage of the tank is appropriately lowered to reduce its Heat income,

2) When the aluminum level in the tank is low, the amount of aluminum output can be reduced or solid aluminum can be added to the tank to increase the aluminum level and increase heat dissipation at the bottom of the furnace so that the furnace is not damaged and Adjust other technical conditions in a timely manner and adjust the electrolyzer to normal operating track.

3) For hot baths caused by uneven anode bottom palms, you can remove the anode from the uneven bottom position. When installing the anode, it can be higher than the original position and lower the bath temperature. When lowering the tank temperature, do not blindly reduce the tank voltage by reducing the pole distance. Clear electrolyte can be used to reduce the electrolyte resistance and enhance heat dissipation in the electrolytic tank to reduce the tank temperature. Individual serious anode lesions can be replaced with residual electrodes.

4) Due to the overheating of the electrolyte caused by the large electrolyte resistance, the large-surface crust can be opened to expose the anode and electrolyte to enhance heat dissipation in the upper part of the electrolytic tank, and at the same time add aluminum fluoride and cryolite powder into the tank. The melting of the mixture requires a large amount of heat to melt the cryolite, which lowers the bath temperature. The mixed aluminum fluoride can reduce the electrolyte molecule ratio.

5) For severe hot baths, you can replace the electrolyte to lower the bath temperature.

The sign that the hot tank is improving is that the anode is working powerfully, the electrolyte is boiling evenly, the surface crust is complete, and the carbon residue is well separated. After that, the working voltage of the tank is gradually reduced, and the upper insulation material is added. According to the specific situation, slowly withdraw the aluminum water to eliminate the precipitation at the bottom of the furnace, so that the electrolytic cell can steadily return to normal operation.
