Abstract

La presente tiene por objeto un procedimiento de cambio de ánodo de una celda de produccion de aluminio por electrolisis ígnea (2) que posee una pluralidad de ánodos (20, 20'). Segun la presente, por un lado, se utiliza al menos una herramienta de manejo de ánodo (13) que posee un elemento de posicionamiento (13b), un elemento de prension (13a) y un sensor de posicion vertical del elemento de prension y se utiliza el sensor de posicion para medir las distancias recorridas verticalmente por el elemento de prension (13a) con respecto a un nivel de referencia N, y, por otra parte, se produce al menos un haz de ondas sonoras o electromagnética (51) en un eje o un plano de referencia determinado (50) y se utiliza el pasaje del ánodo en dicho haz para medir dichas distancias. Se determina la posicion vertical del ánodo de reemplazo en la celda a partir de los valores obtenidos para dichos distancias recorridas y se coloca el ánodo de reemplazo en esta posicion en la ubicacion inicialmente ocupada por ánodo usado (20').The purpose of the present is a method of changing the anode of an aluminum production cell by igneous electrolysis (2) having a plurality of anodes (20, 20 '). According to the present, on the one hand, at least one anode handling tool (13) is used which has a positioning element (13b), a clamping element (13a) and a vertical position sensor of the clamping element and uses the position sensor to measure the distances traveled vertically by the clamping element (13a) with respect to a reference level N, and, on the other hand, at least one beam of sound or electromagnetic waves (51) is produced in a axis or a certain reference plane (50) and the anode passage in said beam is used to measure said distances. The vertical position of the replacement anode in the cell is determined from the values obtained for said distances traveled and the replacement anode is placed in this position at the location initially occupied by used anode (20 ').
