Electrode for a doctor blade for pickling and cleaning metal surfaces

Abstract

An electrode for an electrolytically acting doctor blade (1) for pickling and cleaning both planar and curved metal surfaces, comprising a linear metal element supported on the structure of the doctor blade and electrically connected to the electric circuit for initiating the pickling electrolytic action; a pad made of a felt-like absorbent plastic material, resistant to high temperatures and to the chemicals contained in the electrolytic solution used; characterised in that a the linear metal element consists in a metal wire (8, 38), and a pad (7, 34, 41) having a constant thickness (S), made of a felt-like absorbent plastic material, resistant to high temperatures and to the chemicals contained in the electrolytic solution used, is wrapped therearound; the metal wire being connected to the structure of the doctor blade only at the ends of the doctor blade (25) in the active face of the deformable electrode (2, 20, 33, 35). Different constructive forms of the electrode for doctor blade are described, wherein the metal wire is associated with carbon elements of various shapes to facilitate electrical contact with the pad.
