Abstract: The present invention discloses replaceable cathode choking devices of an aluminum reduction cell which comprises cathode carbon blocks and cathode choking devices placed at the bottom of the aluminum reduction cell. The cathode choking devices are placed on surfaces of the cathode carbon blocks. The cathode choking devices are made of mullite, spinel or zirconite which is high temperature resistant, corrosion resistant and of high specific gravity. The cathode choking devices have a cross-section of semicircular, arc or streamline shape. The cathode choking devices have a height of 50-150 mm and a width of 100-300 mm. The cathode choking devices are elongated block-shaped. The cathode choking devices are placed in a direction along a long side of a cathode of the reduction cell, wherein one or more cathode choking devices are placed as a group. 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 realize the effect of energy saving and consumption reduction.

Abstract: The present invention discloses a cell bottom structure of a reduction cell which comprises a reduction cell and a cathode bus, wherein the bottom of the reduction cell is provided with column-shaped cathode carbon blocks perpendicular to the bottom of the reduction cell, and a lower end of the column-shaped cathode carbon block is connected to the cathode bus. By means of inserting the column-shaped cathode carbon blocks perpendicular to the bottom of the reduction cell and connecting the lower end of the column-shaped cathode carbon block with the cathode bus, such that electrical current that guided from anode carbon blocks is guided through the molten aluminum to the column-shaped cathode carbon blocks and is downwardly guided out, the present invention reduces horizontal electrical current in the molten aluminum, such that the cathode extending into the molten aluminum can effectively reduce fluctuations of the molten aluminum to obtain a stable surface of the molten aluminum, thereby reducing a polar distance between a cathode and an anode and lowering cell voltage so as to achieve the object of lowering electricity consumption.
