Definitions
- the invention relates to a device for carrying out continuous electrolytic deposition processes comprising a rotating cathodic current roller with an electrically conductive surface over its entire usable width and one or more anodes arranged approximately concentrically to the current roller, with the spacing space located between the current roller and the anode is flowed through by an electrolyte containing the metal to be deposited in dissolved form, to which current roller in a peripheral arrangement are assigned means for preventing a coating of the areas not used in electrolytic deposition processes from the current roller.
- a device for the production of electrolytic metal strips is known, for example, from US Pat. No. 2,044,415.
- a driven cathodic current roller forms a spacing space with anodes which are arranged concentrically to the cylindrical surface of the current roller and which are arranged around the current roller at an angle of approximately 160 degrees.
- the electrolyte containing the metal to be deposited flows through the space.
- the metal initially contained in dissolved form in the electrolyte is deposited on the cathodic surface of the current roller. Due to the rotating movement of the current roller, the electrolytic coating can then be removed as a film or thin metal strip after it emerges from the electrolyte and can be fed continuously to subsequent processing steps.
- the entire current roller width is used for the electrolytic deposition processes to form the metal foil. So that the current roller in its edge area in the transition to its end faces is not subjected to an electrolytic coating, which would damage it, a rubber band with a circular cross section is used, which is located on the front edge of the current roller and on a non-conductive, on the Current roller supports the flange arranged on the end face. This sealing rubber band ensures that a current flow to the front of the Current role out and thus preventing electrolytic coating of these areas is avoided.
- this known device is only suitable for producing metal strips or foils in a single width, namely the width of the current roller. However, this device is unsuitable for the production of metal strips of different widths. This known device is also not intended for one-sided electrolytic coating of metal strips.
- a device for one-sided electrolytic coating of metal strips is known from WO 94/10360.
- a metal strip to be coated on the outside is guided in contacting manner around the driven cathodic current roller.
- the metal strip is fed via a deflection roller with the smallest possible distance to the current roller and is continued on the opposite side via a further deflection roller after the coating.
- the metal strip passes through a space through which an electrolyte flows and in which the metal strip is electrolytically coated.
- the space formed by the strip surface and the anode arranged opposite is delimited by seals which can be set up to adapt to different widths of metal strips to be coated in the axial direction of the current roller.
- These seals are supported with a sealing section in each case in the edge region of the metal strip to be coated. These supporting sealing sections contact the surface of the metal strip to be coated at a wrap angle that is so large that there is sufficient tightness when the metal strip enters the electrolyte.
- Electrolytic metal strip production cannot be carried out with an object according to WO 94/10360.
- the invention is therefore based on the object of proposing a generic device in which not only the usable area of the current roller can be set up and the unused areas of the current roller are effectively protected against undesirable electrolytic coatings, but with which both Electrolytic metal strip production and a one-sided electrolytic coating of metal strips is possible.
- the current roller on each side is assigned a shielding tape protruding from the end face over the cylindrical surface of the current roller made of an electrically insulating material which is between the cathodic current roller and the anode or anodes and adjacent to the current roller area used for electrolytic deposition processes (useful area), electrically shielding the edge area of the current roller that is not used in the deposition process and surrounding the current roller at least at the fill level of the electrolyte, the side of a shielding tape facing the useful area pointing in this direction, has paragraph extending over the length of the shielding tape.
- a shielding band expediently a flexible band of electrically non-conductive material, which is arranged surrounding the current roller in the region of the electrolyte, an electrically effective shielding between the anode or the anodes, which are expediently insoluble, and that covered by the shielding band Sections of the current roller serving as cathode created.
- An electrical current flow between the anode and the cathode therefore only takes place in the useful area of the current roller and thus in the areas not covered by the shielding tapes, so that an electrolytic coating is limited to the respective useful area of the current roller.
- the shielding tapes there is no current flow and therefore also no electrolytic coating.
- this has a shoulder directed towards the current roller. This also ensures that there is an edge-thinning layer thickness in the outer edge sections of the metal strip to be produced or coated, which is reduced to zero up to the strip edge, so that the current roller is not coated outside the useful area.
- the device according to the invention is suitable both for the electrolytic production of metal strips or foils and for the one-sided electrolytic coating of metal strips, since the device for protecting the unused current roller sections is based on the principle of electrical shielding and not the principle of liquid sealing, as is the case, for example, with the subject matter of WO 94 / 10360 used, used.
- the edge region of the metal strip to be coated engages in the shoulder of the shielding strips facing the useful area, so that the lateral edge of the metal strip is already electrically shielded to such an extent that an excessive coating of these metal strip sections and a coating of the current roller in that section is protected from an electrolytic coating which borders directly on the area covered by the metal strip to be coated.
- FIGS. 2 and 3 shows an enlarged detail of the area marked “X” in FIGS. 2 and
- the shielding band 9' is supported with its supporting webs 10 'on the electrically conductive outside of the current roller 3. Only in the area of the drain grooves 11' is this edge portion of the current roller 3 in Due to the electrically non-conductive design of the shielding tape 9 ', however, this area of the current roller 3 is electrically shielded so that electrolytic coating of these edge sections is prevented.
- the shielding tape 9' is brought into contact with the outside of the current using suitable tensioning means. roller 3. There is therefore sliding contact between the top of the current roller 3 and the shielding band 9 '.
- the shielding bands 9, 9' are supported in the direction of rotation 4 of the current roller 3 at the end by a stop.
