Abstract

Electrode holder system for electrothermic smelting furnaces comprising current clamps for conducting electric current to an electrode and hydraulic cylinders for moving the electrode up and down. The cylinders are connected to the electrode via an electrode frame and releasable clamping means. At least two vertical rails are arranged parallel to the electrode. The rails are at their upper ends suspended from a suspension frame and have a stopper means on their lower ends. The stopper means represents the lower limit for the movement of the current clamps. The electrode holder system combines regulation of the tip position with automatic feeding of the electrode.
