Abstract
581,625. Furnace hearths and walls. SOC. ANON. POUR L'INDUSTRIE DE L'ALUMINIUM. Sept. 21, 1944, No. 18064. Convention date, Aug. 23, 1943. [Class 51 (ii)] [Also in Group XI] In a furnace for the electrolytic production of aluminium, the hearth is formed by pouring into the furnace shell an artificial carbon mass 1, e.g., ground coke with a binder of coaltar pitch, and then baking it. The carbon mass may be subjected to mechanical vibrations of high frequency as described in Specification 561,496 either before, during or after pouring. The baking is effected by passing a current through the mass 1 between metallic conductors 2 fixed in the furnace bottom and the carbon anodes 4 which are afterwards used for the electrolysis, conducting pieces 3, formed of artificial carbon masses already baked, being arranged within the mass 1 in contact with the conductors 2 and with their upper surfaces just below the surface of the mass 1. To protect the anodes 4 from oxidation, the spaces between them are filled in with granular alumina or powdered coal 5 which is removed after the baking is complete. The baking is carried out slowly, the current intensity being gradually increased up to the value normally used for the electrolysis. The side walls of the furnace may be formed in a similar manner with the use of a template, the carbon mass in this case preferably having its electrical conductivity reduced by the admixture of alumina or residues from the carbon lining of old furnaces.
