Sustainable Mining and Metallurgy

The process of aluminum electrolysis follows the principle of double balance of voltage and energy, and energy balance is an important factor restricting the energy saving of electrolytic cell. In this paper, the factors affecting the heat dissipation of electrolytic cell were analyzed based on the principle of heat transfer, and the measures adopted in the industry were summarized, such as adjusting the ambient temperature, cell temperature, thermal conductivity of the cell, the whole heat dissipation area, flue gas flow rate and so on. This paper points out that adjusting the aluminum level of the electrolytic cell, the flue gas flow rate and the covering material coverage system are commonly used measures to adjust the heat dissipation of the electrolytic cell, which are simple and effective, and the cost is low. Adjusting the cathode lining structure of the electrolytic cell has the greatest influence on the energy balance of the electrolytic cell, and the effect is obvious, but the technical requirements and the cost are the highest. Specific measures need to be based on their own situation.
