ABSTRACT:
A holder assembly (2) for an electrode (1) in an electrothermal smelting furnace is movable suspended from a suspension means and comprises a plurality of contact clamps (3) which are pressed towards the electrode (1) by means of pressure producing means and an externally arranged thrust member (5). The holder assembly (2) is further equipped with means for supplying current to the electrode. The thrust member (5) is formed of the cooling shield which surrounds the electrode and the holder assembly. On the inner surface of the cooling shield (5) a plurality of vertical, current conducting rails (7) are arranged. Sliding contacts (10) arranged on the pressure producing means (4) are thrusted against the rails, providing proper electrical contact. The rails (7) are preferably insulated from the shield (5). The shield (5) may preferably be stationary arranged with respect to the electrode and constitute an integral part of the furnace roof/hood (6).
