The present invention relates to a method for determination of the electrode tip position for consumable electrodes in electric smelting furnaces, which electrodes being submerged in the furnace charge. The voltage between two geometrically displaced points on the outside of the steel wall of the furnace pot is measured during operation of the furnace, said points being situated as close as possible to the electrode for which the electrode tip position is to be determined, and as far away as possible from the other electrodes in the furnace. The electrode current for the electrode for which the electrode tip position is to be determined, is recorded at the same time as the voltage between the two points are measured, whereafter the difference between measured voltage between the two points and measured electrode current is calculated, and where the absolute value of said difference increases when the electrode tip position increases and decreases when the absolute value of said difference decreases.

La présente invention concerne un procédé permettant de déterminer la position des extrémités d'électrodes consommables dans des fours électriques de fusion, lesquelles électrodes sont immergées dans la charge du four. On mesure la tension entre deux points géométriquement distants à l'extérieur de la paroi en acier du four, lorsque le four est en service, ces points étant aussi proches que possible de l'électrode pour laquelle la position de l'extrémité doit être déterminée, et aussi éloignés que possible des autres électrodes du four. On enregistre le courant d'électrode de l'électrode pour laquelle la position de l'extrémité doit être déterminée. Au même temps, on mesure la tension entre les deux points, après quoi on calcule la différence entre la tension mesurée entre les deux points, et le courant d'électrode mesuré. La valeur absolue de cette différence augmente lorsque la position de l'extrémité de l'électrode augmente, et baisse lorsque la valeur absolue de cette différence baisse.
