Abstract
The present invention relates to an electrode holder assembly for self-baking electrodes in an electrothermic smelting furnace. The electrode comprises an electrode casing having vertical fins projecting radially outwards from the casing. A plurality of clamping means are slidably arranged on said fins. The clamping means function both as means for conducting current into the electrode and as means for holding the electrode in position. The clamping means impose only tangentially forces on to the electrode in the baking zone. Protection shields are preferably arranged in lateral direction around the electrode, the shields being arranged between the clamping means or outside. Means for supplying air/gas into the space between the shields and the electrode in order to improve the baking conditions are provided.
