Abstract
The invention relates to an internal liner for an aluminum electrolytic cell, which is characterized in that: the internal liner of the electrolytic cell is built by clay firebricks with high density and low porosity, and the apparent porosity of the internal liner is between 13 and 15 percent. The internal liner for the aluminum electrolytic cell can effectively reduce the erosion degree of electrolyte on the fireproof internal liner, reduces the occurrence degree of unfavorable conditions such as breakage and cell shutting of the electrolytic cell, great loss of an aluminum liquid and the electrolyte, obviously worsened technical and economic indicators, reinforced distortion of a cell shell, improved electrolysis production cost of aluminum, reduced economic benefit and so on due to the fact that the electrolyte and the aluminum are leaked into cracks to dissolve a cathode steel bar caused by lifted furnace bottom, local bending and fine-drawing of the cathode steel bar, and the cracks generated between the cathode steel bar and a cathode carbon block because the cathode carbon block is protruded upwards, and has good functions of further energy conservation, long service life and high efficiency on the aluminum electrolysis production.
