Abstract
The present invention relates to an assembly and a method for feeding electrodes which are used in electrothermic smelting furnaces. The electrode comprises an electrode casing having vertical ribs projecting radially outwards from the casing. A plurality of electrode feeding units, each including a clamping means are arranged around the periphery of the electrode and each clamping means exerts a releasable pressure on a rib, the clamping means imposing only tangentially forces on to the electrode. When feeding the electrode, the pressure on one of the clamping means is temporary released and the clamping means is moved in vertical direction relative to the electrode, whereafter the pressure on the clamping means is reactivated. This is done for every electrode feeding unit with a preset time-delay between the movements. When all the electrode feeding units have been moved one at a time, all the electrode feeding units are moved together in vertical direction. The clamping means are formed of two substantially identical reversed parts which are hinged around a central member.
