| Abstract: |
| Effect of comprehensive energy saving technology on level of current flow of composite cathode in molten aluminum during aluminum electrolysis process was researched with computer analog simulation. The simulation results show that comprehensive energy saving technology with high conductive composite stabilized steel core can significantly reduce size of current level of cathode in molten aluminum, reduce electrolyte aluminum liquid interfacial deformation, improve stability of magnetic fluid of electrolyzer, and cell voltage and current efficiency is improved to achieve energy saving effect. In order to verify simulation results, comprehensive energy saving technology industrialization composite steady flow is tested in 300 kA series of electrolytic cell. With application of comprehensive energy saving technology with high electrolytic current composite conductive steel rod as core, current level of cathode is significantly reduced, electrolyte aluminum liquid interfacial deformation is very small, operation stability of electrolytic cell production is improved, and DC power consumption of per tonnage aluminum is lower than that of series of traditional cells, 201 technology cells and double steel bar technology cells. |
