Inclined flange linings for cathode units are gaining ever greater attention from planners drawing up new designs for aluminum electrolyzers. Moreover, the cathode and anode areas are becoming approximately equal; their current loads are correspondingly equal, substantially improving the hydrodynamics in bath shafts, reducing the consumption of carbon-graphite and heat-insulating materials, as well as reducing the cathode mass and its cost. Now, we have the first positive experience in the use of such linings. Nevertheless, designers and planners have raised a number of questions. Inclining flange linings leads to a substantial redistribution of forces being transmitted from the hearth side to the shell. How is this reflected in the operation of the hearth, the flange block, and the shell wall?
