摘要： A system is disclosed for lowering (“slipping”) and/or raising (“back slipping”) electrodes relative to an electrode column. The system includes an electrode column having at least one slipping sleeve and a power clamp, each of which apply a radial clamping force to the electrode. The magnitudes of the clamping forces are selected such that application of a downwardly directed axial force on the one or more slipping sleeves, in combination with the weight of the electrode, are sufficient to overcome the resistive force of the power clamp, resulting in downward movement of the electrode without release of the clamping forces. Electrode columns having two movable slipping sleeves are also capable of raising the electrode relative to the furnace without release of the clamping forces.
