Dry anti-penetration castable to extend the life of the cathode liner has a positive effect. On the one hand can buffer the cathode carbon block uplift; the other hand can strengthen the bottom of the security The ability to reduce the heat loss at the bottom of the tank and to increase the temperature of the cathode carbon block itself and to reduce the temperature gradient between the upper and lower sides of the cathode carbon block. Due to dry Dry anti-penetration castable can be infiltrated with the electrolyte to produce a layer of 5 to 15 mm thick, dense glass-like kaolin barrier layer: This barrier, on the one hand, prevents the electrolyte from continuing to penetrate the lower part and protect its lower part The temperature of dry anti-penetration castable is not destroyed; the other hand, because the barrier layer with plasticity and particle layer has a certain compressibility, can effectively alleviate the furnace uplift, Deformation of the tank shell and other issues. Therefore, in the aluminum furnace in the furnace process, it can be placed directly on the insulation brick, the compaction of the upper part of the upper directly placed.
