Abstract (en)

[origin: US4589967A] Cell for the fusion-electrolytic production of aluminum which consists of a steel shell lined with graphite blocks, a heat-retarding insulation layer between the shell and the lining and cathodic bus bars inserted into the lining. Features of the invention are (a) the lining consists of graphite blocks with a heat conductivity of 80 to 120 W/mxK, an electric resistivity from 6 to 13 mu OMEGA m and an accessible pore volume of at most 22%, (b) the insulating layer contains at least two partial layers with a heat conductivity of 0.1 to 0.2 and 0.8 to 1.2 W/mxK, (c) the thickness ratio of the lining and the insulating layer is 1.5 to 3.0.
