Abstract
THE PRESENT INVENTION DISCLOSES REPLACEABLE CATHODE CHOKING DEVICES OF AN ALUMINUM REDUCTION CELL WHICH COMPRISES CATHODE CARBON BLOCKS (1) AND CATHODE CHOKING DEVICES (2) PLACED AT THE BOTTOM OF THE ALUMINUM REDUCTION CELL. THE CATHODE CHOKING DEVICES (2) ARE PLACED ON SURFACES OF THE CATHODE CARBON BLOCKS. THE CATHODE CHOKING DEVICES (2) ARE MADE OF MULLITE, SPINEL OR ZIRCONITE WHICH IS HIGH TEMPERATURE RESISTANT, CORROSION RESISTANT AND OF HIGH SPECIFIC GRAVITY. THE CATHODE CHOKING DEVICES (2) HAVE A CROSS-SECTION OF SEMICIRCULAR, ARC OR STREAMLINE SHAPE. THE CATHODE CHOKING DEVICES HAVE A HEIGHT OF 50~150MM AND A WIDTH Of 100~300MM. THE CATHODE CHOKING DEVICES (2) ARE ELONGATED BLOCK-SHAPED. THE CATHODE CHOKING DEVICES (2) ARE PLACED IN A DIRECTION ALONG A LONG SIDE OF A CATHODE OF THE REDUCTION CELL, WHEREIN ONE OR MORE CATHODE CHOKING DEVICES (2) 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.
