Abstract

Procedimiento para grafitizar bloques catódicos para lo obtención electrolítica de aluminio según el método de la grafitización longitudinal, caracterizado porque los bloques catódicos están dispuestos en un horno de grafitización longitudinal de modo que la distancia de sus superficies extremas esté comprendida entre 25 y 150 mm, y porque el paso de la corriente entre los distintos bloques catódicos es proporcionado por cuerpos conductivos, y porque cada dos bloques catódicos descansan sobre los cuerpos conductivos de tal manera que el contacto entre los bloques catódicos y los cuerpos conductivos sea proporcionado por la fuerza del peso que actúa sobre los bloques catódicos, los bloques catódicos así obtenidos y su uso para la reducción electrolítica de óxido de aluminio.Procedure for graphitizing cathode blocks for obtaining electrolytic aluminum according to the method of longitudinal graffiti, characterized in that the cathodic blocks are arranged in a longitudinal graphing furnace so that the distance of their extreme surfaces is between 25 and 150 mm, and because the passage of the current between the different cathode blocks is provided by conductive bodies, and because every two cathodic blocks rest on the conductive bodies such that the contact between the cathode blocks and the conductive bodies is provided by the force of the weight that It acts on the cathode blocks, the cathode blocks thus obtained and their use for the electrolytic reduction of aluminum oxide.
