Реферат: The present invention relates to a method for estimating the electrode tip position for submerged, consumable electrodes in electric smelting furnaces. The electrode tip position for an electrode is estimated based on the position of the electrode holder and a function for consumed electrode per unit of time. According to the invention it is established an upper and a lower uncertainty range for estimated electrode tip position, which upper and lower uncertainty ranges are increased during normal operation of the furnace and where the size of the upper and lower uncertainty ranges is updated by manual sounding of the electrode and/or by weighing of the electrode and/or by vertical movement of the electrode.
