Abstract (en)

[origin: DE10164013C1] Longitudinal graphitization of cathode blocks for electrolytic production of aluminum comprises arranging the blocks with a gap of 25 - 150 mm between their end faces. Conductive moldings are placed between the blocks and the contact between the two is controlled by the weight acting on them.
