Abstract
An improved holder assembly for self-baking electrodes in an electrothermal smelting furnace comprises a plurality of contact clamps which are pressed towards the electrode by hydraulic presses between the clamps and a cylindrical body arranged externally around the clamps. The holder assembly is further equipped with means for conducting current, coolant and/or pressure agent to the contact clamps. The contact clamps extend at least up to the zone where the raw, unbaked electrode paste is unaffected by the heat from the smelting furnace. The cylindrical body extends up from the area of the presses. The cylindrical body is slidably arranged with respect to the contact clamps. Each of the contact clamps is separately suspended and may be moved individually with respect to each other and with respect to the surrounding cylindrical body.
