Abstract (en)
An apparatus for the electrical treatment of ferrous and nonferrous metal wires, in line with a drawing apparatus, including: a station (2) for descaling and brushing a layer of oxides and calamine that is present on the metal wires that enter the apparatus; a station (3) for electrolytic pickling by adjustable retention in a bath of acid or basic solution; a washing station (4); and stations (5,6) for the further treatment of the wire that exits from the washing station before being sent to a drawing apparatus. The apparatus further includes a crystalization device which is suitable to keep the concentration of the substances descaled from the metal wires below a preset value in order to extend the useful life of the pickling bath that is present in the pickling station. <IMAGE>
