摘要： PURPOSE:To electrolyze the surface of a metallic material on the spot and to obtain a high-quality surface by holding the paste contg. an electrolyte between the metallic material and a counter electrode, and supplying an electric current between the material and the counter electrode. CONSTITUTION:The metallic material 4 to be treated is placed on an insulating holder 7. The paste 3 is coated on the surface of the material 4. The paste 3 is obtained by adding an electrolyte such as sodium sulfate and a paste forming agent such as sodium polyacrylate to water, and kneading the mixture. The counter electrode 2 provided with a cover 1 capable of being impregnated with the paste 3 and capable of holding the paste 3 is then arranged on the paste 3. The counter electrode 2 and the material 4 are respectively connected to the negative pole and positive pole of a DC power source 6 through an electric wire 5. As a result, the surface of the material 4 can be electrolytically cleaned uniformly, easily, and rapidly.

摘要： PURPOSE:To efficiently remove scale sticking to the inside and outside of a steel pipe by arranging means of concentrically holding the steel pipe between outer and inner movable electrodes, moving the electrodes in the vertical direction and supplying electric current between the electrodes and the steel pipe. CONSTITUTION:A cylindrical outer movable electrodes 5 and an inner movable electrode 6 are concentrically held and a steel pipe 4 is concentrically put between the electrodes 5, 6 so as to avoid electrical contact with the electrodes 5, 6. Electric wires 14 connected to the electrodes 5, 6 are wound up and unwound through pulleys 15 to move the electrodes 5, 6 in the vertical direction. The pipe 4 is vertically held on a support stand 9 fixed on the bottom of a pickling bath 2. A power source 10 is connected to the electrodes 5, 6 and the pipe 4 and electric current is supplied between the electrodes 5, 6 and the pipe 4 to electrolytically pickle the pipe 4. Thus, current density between the pipe 4 and the electrodes 5, 6 is made uniform and the entire surface of the pipe 4 can be uniformly descaled.

摘要： PURPOSE:To efficiently remove rigid oxide scale sticking to both sides of thick plates in a short time by arranging means of parallel moving electrodes placed opposite to the thick plates and supplying electric current between the thick plates and the electrodes. CONSTITUTION:Thick plates 4 are vertically held in a pickling tank 2 with a support stand 5 and stoppers 7. Movable electrodes 6 are vertically placed with holding means such as suspending members 9 so that each of the electrodes 6 confront at least one side of each of the plates 4. The members 9 are wound up and unwound through pulleys 11 to move the electrodes 6 upward and downward in the vertical direction. A power source 14 is connected to the plates 4 and the electrodes 6 and electric current is supplied between the plates 4 and the electrodes 6 to electrolytically pickle the plates 4. Thus, the treatment time required to descale the plates 4 can be shortened.

摘要： PURPOSE:To efficiently remove oxide scale sticking to the inside and outside of a steel pipe in a short time by arranging means of concentrically holding the steel pipe between outer and inner electrodes, moving the electrodes and supplying electric current between the electrodes and the steel pipe. CONSTITUTION:An inner electrode 6 of a small diameter is concentrically set in an outer electrode 5 of a large diameter and a steel pipe 4 is concentrically put between the electrodes 5, 6 so as to avoid electrical contact with the electrodes 5, 6. The pipe 4 is supported on the bottom of a pickling bath 2 through plural support stands 8. A truck 110 moving on rails 111 is connected to the outer electrode 5 with a suspending jig 112 and the electrode 5 is moved in the longitudinal direction of the pipe 4 by moving the truck 110. The inner electrode 6 is also moved in the longitudinal direction of the pipe 4 by travelling a tractive rope 122 wound around pulleys 121. A power source 14 is connected to the electrodes 5, 6 and the pipe 4 to supply electric current for electrolytic pickling. Thus, bubbles of gaseous hydrogen can be effective removed and uniform satisfactory descaling can be carried out.

摘要： PURPOSE:To carry out excellent descaling in a short time by concentrically arranging an electrode on the inner face side and outer face side of a steel pipe, and electrolytically pickling the steel pipe. CONSTITUTION:The electrolytic pickling device 1 for a steel pipe 4 is formed with cylindrical outside electrode 5 and inside electrode 6, a means for supporting the electrodes 5 and 6, a steel pipe holding means, and energizing means 14, 15, and 18. The outside electrode 5 has an inner diameter larger than the outer diameter of the steel pipe 4 to be electrolyzed. The inside electrode 6 is positioned in the inner side of the electrode 5, and has an outer diameter smaller than the inner diameter of the steel pipe 4. The electrodes 5 and 6 and the steel pipe 4 in the gap between the electrodes 5 and 6 are concentrically supported by the electrode supporting means and the steel pipe holding means. By such a constitution, the steel pipe 4 horizontally arranged in the bath filled with an acidic soln. is electrolytically pickled.

摘要： PURPOSE:To quickly and uniformly remove scale from a thick metal plate by holding the thick metal plate and a plate electrode face to face in a tank filled with acid solution and applying a current between them. CONSTITUTION:In a pickling tank 2 filled with acid solution 3, a thick metal plate 4 and a fixed electrode 6 are fitted vertically by turns and at equal intervals and the bottom end part is held by a support 5 and a stop material 7. The thick plate 4 is connected with a plus terminal of a power source 14 through a contact electrode 12 and an electrical wire 15 and the electrode 6 is connected with a minus terminal of the power source 14 through the contact electrode 11 and the wire 15. In this structure, when an electric current is applied from the power source 14 between the thick plate 4 and the electrode 6 to remove scale from the thick plate 4, the acidic ag. solution 3 between the thick plate 4 and the electrode 6 and the acidic ag. solution 3 on the circumference cause natural circulation to conduct uniform and non-defective electrolytic pickling without deteriorating mechanical properties of the thick plate 4.

摘要： PURPOSE:To efficiently remove the oxide scale on a steel pipe in a short time by concentrically and vertically arranging cylindrical outer electrode and inner electrode in an aq. acidic soln., holding concentrically a steel pipe in the gap between both electrodes, and carrying out electrolytic pickling. CONSTITUTION:In the pickling soln. 3 in a pickling bath 2, the cylindrical outer electrode 5 and inner electrode 6 are vertically and concentrically set on a holder 9, and the steel pipe 4 is held in the gap between both electrodes 5 and 6 by an optional holding means through spacers 7 and 8. The steel pipe 4 and both electrodes 5 and 6 are connected to an electric power source 10 by an acid-resistant covered conductor 14 through clipper electrodes 11, 12, and 13. Under such a constitution, the steel pipe 4 and both electrodes 5 and 6 are energized to remove the oxide scale deposited on the inner and outer sides of the steel pipe 4. The pickling soln. 3 is sent, as required, to a refrigerator 150 from a suction pipe 151 and cooled, the cooled soln. is returned to the pickling bath 2 through a discharge pipe 152, and an increase in the temp. of the pickling soln. 3 is prevented. By this method, the scale can be rapidly and efficiently removed.
