Abstract

Procedimiento de grafitización de bloque catódicos para la obtención electrolítica de aluminio según el método de la grafitización longitudinal, en el que los bloques catódicos están dispuestos en un horno de grafitización longitudinal de modo que se solapan en su longitud en al menos 500 mm y se mantiene una distancia mínima de 5 mm entre las superficies longitudinalmente dirigidas de los bloques catódicos, proporcionándose el paso de la corriente entre los distintos bloques catódicos por medio de cuerpos conductivos y estando los bloques catódicos y los cuerpos conductivos colocados uno sobre otro 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 fabricados y su uso en la obtención de aluminio.Method of graffiti of cathodic block for the electrolytic obtaining of aluminum according to the method of longitudinal graffiti, in which the cathode blocks are arranged in a longitudinal graffiti furnace so that they overlap in their length by at least 500 mm and are maintained a minimum distance of 5 mm between the longitudinally directed surfaces of the cathode blocks, the passage of the current between the different cathode blocks being provided by means of conductive bodies and the cathode blocks and the conductive bodies being placed one above the other in such a way that the Contact between the cathode blocks and the conductive bodies is provided by the force of the weight acting on the cathode blocks, the cathode blocks thus manufactured and their use in obtaining aluminum.
