Abstract

Bloques catódicos grafitizados para producir aluminio por reducción electrolítica de óxido de aluminio en un bano de criolita fundida, caracterizados porque los bloques catódicos presentan un perfil de forma de V de su resistencia eléctrica en toda su longitud, aumentando la resistencia hacia los extremos y presentando en el centro de los bloques catódicos un punto de discontinuidad, procedimiento para su fabricación y su uso en la producción de aluminio.Graffiti cathode blocks to produce aluminum by electrolytic reduction of aluminum oxide in a molten cryolite bath, characterized in that the cathode blocks have a V-shaped profile of their electrical resistance throughout its length, increasing resistance towards the ends and presenting the center of the cathode blocks a point of discontinuity, a procedure for its manufacture and its use in the production of aluminum.
