<p>The present invention discloses a method of configuring energy saving high and low cathodes of an aluminum reduction cell, said method comprising disposing cathode carbon blocks and cathode steel rods (3) at the bottom of the aluminum reduction cell, the cathode carbon blocks being formed by staggering high cathode blocks (1) and low cathode blocks (2) with different thicknesses. Both sides of the portion of each of the high cathode blocks (1) higher than each of the low cathode blocks (2) must be machined into bevels or arc angles, so as to achieve a good choking effect. The present invention can better improve the stability of molten aluminum-electrolyte interface within the aluminum reduction cell, decrease the polar distance effectively during normal production, and achieve a lower operating voltage of the reduction cell, thereby saving energy and reducing energy consumption</p> |
