ABSTRACT:
A method of prolonging the useful life of a partially consumed electric arc furnace electrode which comprises holding the electrode in a fixed position, moving a plurality of electrode protection sheets substantially radially of the major axis of the electrode towards the electrode and pressing the sheets into contact with the electrode for a sufficient time to adhere the sheets to the surface of the electrode.
A frame adapted to receive at least a portion of the electrode, a plurality of carriages each reciprocable in a direction radial of the major axis of the electrode, when located in the frame, each carriage being adapted to support a protective sheet, means to urge each carriage towards the electrode, and a plurality of rollers mounted on the frame each rotatable about an axis perpendicular to the plane including the centers of the rollers and the longitudinal axis of the electrode, and each roller being biased toward the electrode.
