The present invention relates to a holder assembly for electrodes in an electrothermal smelting furnace. The holder assembly comprises a plurality of contact clamps which are pressed towards the electrode by means of pressure producing means and an externally arranged thrust member. The holder assembly is further equipped with means for communicating current, coolant and pressure agent to the contact clamps. The holder assembly is constructed as a single integrated unit where current, coolant and pressure agent are conducted through the same supply pipes. The supply pipes serve additionally as support for the holder and consequently the electrode. The pressure producing means is constructed as an integral part of the contact clamps while the supply pipes are welded on to the contact clamps. The holder assembly has a total outer diameter which is less than the internal diameter of the suspension casing, whereby the entire holder assembly may be lifted up or lowered down inside the suspension casing during maintenance or substitution of the holder assembly. |
