Definitions

  • the present invention relates to a current roller for an electrolytic Coil coating line.
  • a current role generally has the task of that of coating anodes tape passing current back to a rectifier due.
  • the strip to be coated is passed horizontally through a Coating cell led, the current rollers in front and behind the cell are arranged, lie on the belt from above or below and with the help of a rubberized counter roller a line pressure exercise on the tape.
  • Roll circumferential speed is determined by the line contact between Band and current roll the current from the band to the current roll transmitted and from this via slip ring systems to the rectifier recycled.
  • the strip to be coated is used in vertical coating systems after leaving the coating cell via current rollers, the at the same time also deflection rollers are deflected by 180 °, so that Belt can enter the next coating cell.
  • the current role has in this case not only power transmission, but also tape management tasks. Because of the bending stiffness of the bands, but also because of the relatively large distances between the coating cells the current roller for vertical systems is relatively large in diameter perform.
  • Another The heat source is the wrapped band, which is also through warmed the internal electrical resistance.
  • band thicknesses in Range below 1 mm strip thickness the strip temperature can be values over 100 Reach ° C, with appropriate heating of the current roller.
  • the current roller is in principle a round hollow body formed, the outer jacket of an acid-resistant and current-conducting Metal.
  • the hollow body is partial or complete filled with cooling water, with cold Introduce water and drain heated water over the other spigot becomes.
  • Another known solution provides for the cavity with displacement bodies largely fill out, creating the latent water mass inside the current roller is reduced, but still the problem of uncontrollable cooling remains.
  • US-A-2 526 312 discloses a current roller for an electrolytic coil coating system known, wherein the current roller has a roller axis, wherein the current roller has a roller jacket with an inner and an outer jacket surface and has two substantially cylindrical bodies, the Basic body cylindrical surfaces, facing and facing away from each other Have sides.
  • the basic bodies are with the roller shell by a press fit and thus inextricably linked.
  • the object of the present invention is a current roller to create, which avoids the aforementioned disadvantages, thereby can be produced with low costs and effort and also that No need to reserve parts of entire roles.
  • the task is accomplished by a current roll for an electrolytic coil coating line, solved with a roller axis, in which the current roller from a roller shell with a Inner wall and an outer wall, which is around the outer surfaces of two, each other opposite and coaxially arranged, cylindrical base bodies attached is, the base body are releasably connected to each other and the cylinder jackets the base body has cooling channels for a cooling liquid.
  • roller casing as such easily replaceable, so that spare parts can be kept whole current rolls is no longer required.
  • the current roller can be produced particularly cost-effectively if the base body is made of normal steel consist and the roller jacket from an acid-resistant and electrically conductive Material, e.g. Stainless steel.
  • the cylinder jackets of the base body are designed to be electrically insulating, that is Current flow in the roll jacket easier to control. This can ensure even heating the current role can be guaranteed.
  • the electrical insulation of the cylinder jackets can e.g. by using a hard, acid-proof, electrically insulating material Layer are provided.
  • roller shell and base body The releasable attachment of the roller shell and base body is particularly easy, if the basic bodies correspond to one another and run parallel to the roller axis Through holes for fasteners, e.g. Tie rods.
  • roller shell 1 for an electrolytic one Coil coating system from a roll shell 1 and two base bodies 2, 3.
  • the roller shell 1 is essentially hollow cylindrical and has an inner wall 4 and an outer wall 5. It consists of an acid-resistant, electrically conductive material, e.g. Stainless steel.
  • On the inner wall 4 of the roll shell 1 is a concentric welded around a roller axis 6 rotating inner ring 7. As can be seen, the inner ring 7 is arranged centrally.

  • the basic body 2, 3 consist of mild steel. You fill the roll jacket 1 in essential, preferably even a perfect fit.
  • the basic body 2, 3 thus have mutually facing sides 9, facing away from one another Pages 10 and the roller jacket 1 facing cylinder jackets 11.
  • the cylinder jackets 11 are hard, acid-resistant and electric insulating layer.
  • the layer can, for example Oxide ceramics exist in which to avoid porosity Fillers are introduced. Such a coating is inexpensive and easy to apply. It protects the cylinder jackets 11 also against corrosion by a coolant (water) and also against possible electrolytic vapors.
  • the cylinder jackets 11 are thus designed to be electrically insulating.
  • Both the roller shell 1 and the base body 2, 3 are here arranged symmetrically with respect to the axis 6, which in the following is also referred to as the roller jacket axis.
  • the base bodies 2, 3 have through holes 12.
