A steel treatment system includes a ladle having a cover, a heating electrode mounted to extend through an opening in the cover, a casing surrounding the electrode and including lower, intermediate and upper sections, and a seal mounted at the cover about the opening for forming a seal with the lower section of the casing. A clamp device is mounted on the intermediate section of the casing and extends therethrough for clamping the electrode and for fixing the relative axial position of the electrod with respect to the casing. An actuator is fixedly supported at a level above the clamp device and is operatively connected to the casing to move the casing and the electrode downwardly. First guide rollers act on the lower section of the casing, and second guide rollers act on the upper section of the casing for ensuring axial movement of the casing and electrode.
