Abstract (en)
[origin: EP0517100A2] An improved electrolytic cell for the production of aluminium by molten-soft electrolysis using a continuous anode system and pre-fired anode blocks is proposed. The novel cell embodies, on the one hand, a new mounting system for the anode blocks, in which compressed granular packings made of carbon-containing material which are used for mounting and current conduction are placed at the long sides of the anode blocks. On the other hand, the cathode blocks of the cell may be placed individually at a distance from one another and from the cell-floor lining. A collecting tank for the aluminium deposited is formed underneath the cathode blocks. In this case, the cathode blocks may be roof-like or of half-barrel shape, the lower side of the anode blocks being shaped so as to match the shape of the oppositely situated cathode blocks.
