At the in This method described dives a wire-shaped Intermediate in a received in a tub treatment solution a and partially circulates in the treatment solution submerged roller 2. In execution of the known Procedure must to ensure a sufficiently long Residence time of the intermediate within the treatment solution either a very large bath for the treatment solution be provided or a particularly low conveying speed be set for the intermediate. Furthermore, in US-A-36 76 32 methods for the Treating septa described where the wires are outside a departmentsbeides arranged pulleys circulate.
  • the invention has for its object to provide a method with which these are solved and one suitable for carrying out this method Specify device.
  • the electropolishing process under a particularly efficient continuous process when the intermediate product is conveyed through the electrolyte bath, preferably with a conveying direction of the intermediate product arranged behind the electrolyte bath and on the intermediate product attacking conveyor by the Electrolyte bath is pulled.
  • the inventive Device preferably a conveyor with two mutually parallel roller axes having Conveyor rollers, wherein the wire-shaped intermediate product is trapped between these conveyor rollers and through Rotation of the conveyor rollers is pulled through the electrolyte bath.
  • the residence time of the wire-shaped intermediate in The electrolyte bath may vary depending on the material properties of the intermediate, such as surface finish after leaving the electrolyte bath, set when the conveying speed is dependent on controlled by these material properties.
  • the effectiveness of the invention Electropolishing process also be promoted by that the GleichstrornPark the anodic to that in the Electrolyte bath recorded intermediate coupled DC source depending on the material properties of the Intermediate, such as the surface texture after Leaving the electrolyte bath, is controlled.
  • the electropolishing method according to the invention is customary using sulfuric acid and phosphoric acid (35-45%) carried out, preferably omitting chromic acid becomes.
  • the electrolyte bath can be different Contain additives or brighteners. To ensure a trouble-free further processing of the wire-shaped intermediate product after passing through the electrolyte bath it is important that residues of the electrolyte completely from the wire-shaped intermediate to be removed. This will be the Intermediate product after carrying out the electropolishing process expediently cleaned accordingly, what it preferably passes through another stationary cleaning device.
  • This further stationary cleaning device may have a plurality from in the conveying direction of the intermediate product in a row arranged cleaning stations, such as water baths, so as to allow complete purification of the intermediate to reach and a carryover of electrolyte residues to exclude in other processing stages.
  • the preservation device expediently also goes through so as to be a continuous process receive.
  • the sawtooth wire in carrying out this process continuously from a uncoiler is withdrawn, then first to the Performing a mechanical cleaning designed cleaning device passes through, then the electrolyte bath passes through, wherein it is substantially helical in the electrolyte bath revolves so as to achieve a long residence time, after leaving the electrolyte bath another cleaning device goes through to remove electrolyte residues, then a preserving device passes through to subsequently presented to a take-up reel and wound up on it be, with the necessary conveyor appropriately between the preservation device and the Take-up reel is arranged and has two conveyor rollers, between which the intermediate product is trapped.
  • FIGS Drawing shows a schematic representation of a For carrying out the method of the invention serving inventive Contraption.
  • the device shown in the drawing consists in essentially from a decoiler 10, on which a wire-shaped Intermediate in the form of one already with saw teeth provided with wire, one to carry out designed a mechanical purification of this intermediate Cleaning device 20, an electrolyte bath 30, a for rinsing the electrolyte bath leaving intermediate designed further cleaning device 40, a preserving device 50, a conveyor 60 and a take-up reel 70.
  • the conveyor 60 includes two parallel to each other running roller axes having conveying rollers 62 and 64, between which the intermediate product is trapped. Go berserk the conveyor rollers 62 and 64 in the in the drawing the arrows P indicated directions, the sawtooth wire. 5 in the direction indicated by the arrow P 'from the unwinding axis 10 deducted. After leaving the uncoiler 10 the sawtooth wire 5 is first with a guide roller 12 a substantially horizontally extending track deflected and then introduced into the cleaning device 20. In this Cleaning device 20 is the sawtooth wire with two cleaning rollers 22 and 24 mechanically cleaned, instead of the cleaning rollers and brushes and / or slurry discs can be used. After leaving the cleaning device 20, the sawtooth wire 5 in the course of by the Conveyor 60 caused promotion in the direction of conveyance behind the cleaning device 20 arranged electrolyte bath 30 introduced.
  • the sawtooth wire rotates 5 are substantially helical two parallel to each other extending roller axes exhibiting and within the electrolyte bath 30 arranged pulleys 33 and 34th
  • the sawtooth wire 5 Anodisch to an externally controllable DC power source (not shown), wherein the direct current intensity in the electrolyte bath depending on the surface properties of the Sawtooth wire is controlled to provide optimal treatment of the sawtooth wire to ensure within the electrolyte bath.
