Abstract
PURPOSE: To protect a brick of a furnace bottom from erosion due to an electrode bath by providing a carbonaceous substance coated iron plate to an upper surface of a lower part of a carbonaceous electrode of the furnace bottom for the aluminum electrolytic furnace lined with the brick.
CONSTITUTION: An iron plate is sprayed or brush coated with a carbonaceous substance dispersed in a solvent or immersed in a dispersion of said carbonaceous substance and, further, coated by the pyrolysis of a hydrocarbon, the vapor deposition of said carbonaceous substance and the like to prepare the carbonaceous substance coated iron plate 11. As the carbonaceous substance, for example, a graphite, a coal or the like are used and, as a dispersing medium thereof, for example, Fron, trichloroethane or the like are used. Said plate 11 is provided to a boundary part of a carbonaceous cathode block 5 and a brick 9. Further, said plate may be provided between bricks of an intermediate part of the brick 9 or may be provided in two layers of said part and the boundary part. The bath permeation can be prevented by said iron plate 11 and the erosion of the brick 9 due to the bath and/or a metal is eliminated.
