Description
Technical field
The invention belongs to the aluminum electrolysis technology field, be specifically related to a kind of aluminium cell of ability slowing down cathode protruding abrasion.
Background technology
Industry is at present gone up the metallic aluminium of producing and is all produced with fused salt electrolysis process, and its specific equipment is that liner is the electrolyzer of blacking (or silicon nitride combined silicon carbide brick), is refractory materials and lagging material between carbon lining and the steel pot shell.The bottom liner of electrolyzer is the carbon piece that its bottom is equipped with the conduction rod iron, and this carbon piece is called the cathode block of electrolyzer.Stick with paste to make firm by ramming with carbon element between cathode block and the cathode block and be connected, many cathode blocks and between them ramming paste form the bottom carbon cathode of electrolyzer.The bath voltage of common industrial cell is about 4.0～4.3 volts, and pole span is between 4.0～5.0cm.At present why industrial aluminum electrolysis bath can also reduce significantly that reason that pole span makes the electrolytic bath loss of voltage is in the existing industrial aluminum electrolysis bath owing to caused the very big fluctuation of negative electrode liquid aluminum generation when the effect of electromagnetic force is overflowed from anode surface and electrolyte melt with anodic gas; If the flow velocity of this fluctuation and wave amplitude can be minimized; The pole span and the bath voltage of current electrolysis groove are reduced, thereby reach the purpose that reduces the aluminum electrolysis power consumption significantly.For this reason; CN200710010523.4 has proposed a kind of aluminium cell of novel cathode structure; The electrolyzer of this novel cathode structure has played the result who reduces the aluminum electrolysis power consumption significantly really after using in the industry; But find also that in practice the height of the bulge-structure on its cathode surface of the electrolyzer of this novel cathode structure can reduce gradually, its spending rate is about 2～4cm/; The erosion and the destruction of carbon cathode lattice surface when in general this consumption is mainly derived from the chemosmosis of sodium in the aluminium liquid, and flowing of negative electrode aluminium liquid then causes coming off of carbon cathode surface to cause to washing away of carbon cathode surface.
Summary of the invention
To the problem that above-mentioned prior art exists, the present invention provides a kind of ability slowing down cathode abrasive aluminium cell, solves the protruding low problem of life-span because of caused by physics, chemical abrasion of cathode surface.
Aluminium cell of the present invention has the cathode block convexity, is specially: along its length limit portion is processed with bulge-structure on each cathode block, is called the length direction convexity; Or, be called the width convexity in cathode block top processing the perpendicular convexity of length direction with cathode block; Or in the cathode block top portion simultaneously the processing length direction protruding with the width convexity.
