Abstract
The invention relates to a system for regulating the depth of immersion of melting electrodes in electrical slag remelting furnaces, consisting of an apparatus for the detection of the resistance and for changing this resistance upon the spatial displacement of the end of the electrode within the slag layer, a signal corresponding to the resistance being relayed to a regulating system for the electrode drive.
