CELLA DI ELETTROLISI PER LA PRODUZIONE DI ALLUMINIO

摘要

The amount of bulging and cracking in the carbon floor of an electrolytic reduction cell for the production of aluminium is reduced by the provision of a recess in the steel container which accommodates the carbon floor as it expands. The recess is filled with a first material which is easily compressible and a second material which deforms only at a relatively higher load and transmits the expansion forces to the steel container without producing any permanent deformation thereof.
