  • the roller shaft is also made individual elements.
  • the roller casing is arranged side by side Slices formed. Between the discs is a drainage to the thermal Insulation and one insert for electrical insulation provided. Of the multi-part roller shell is therefore thermally and electrically on the roller shaft stored isolated.
  • the known object therefore fulfills only the task inductively generated heat supplied to the rolled product. Also leave such slices interruptions on the roller surface and do this unusable. This is already the goal, unwanted charges by friction between a smooth roll shell of the roll and the metal product too avoiding and not achieving the goal of isolating electric heating currents.
  • the invention is based on the object, such electrical currents and sparking to prevent, so that the mentioned damage does not occur any more can.
  • roller shell at least at the roll ends each electrically and / or thermally insulated is mounted on the roller shaft to the effect that between the roller shell distributed at the roller ends and the roller shaft respectively over the circumference arranged, single insulator are provided.
  • a roller table roller is suitable for roller tables or Roller table parts in the field of inductive heating of the product and induced electric fields as well as general differences of the electric potential between a rolled or continuously cast product and the roller table roller where electrical Currents and sparking can cause surface defects.
  • Such a roller table roller can also be used to the Heat exchange by conduction between the heated by the product Roller shell with the generally cooled roller shaft (roller axis) largely to prevent.
  • the insulating body can thereby for centering the roll shell used on the roller shaft and / or for torque transmission become.

  • the axial Fuse consists of welded on the front sides of the bearing sheet metal rings.
  • roller shell and the roller shaft in principle from each other are separated and are exclusively connected via the insulating body, can by means of axial securing a floating bearing and a fixed bearing between the Roller shell and the roller shaft be formed. This can cause thermal stress and thermal expansions are absorbed.
  • roller shell in several, spaced on the roller shaft roller sheath sections arranged respectively arranged distributed over the circumference, the roller shaft centering and the Drive torque transmitting Isolierkörpem is articulated.
  • roller sheath sections separated from the roller shaft and become exclusive connected via the insulator described.
  • the insulating body is designed as a tapered bearing, its cone inner ring and / or its cone outer ring and / or its Tapered rollers each forming insulating body. It can because of the short roller sheath sections by heating and length expansion in the axial direction arising game are neglected, so no arrangement in Losund Fixed storage is required. In this case, especially electrical currents in Directed axis direction.
  • the inclination of the cone is to be chosen so that due to the elongation of the roller mantle the outer cone on the inner cone another Position takes and thus largely compensates for the expansion of the diameter.
  • Another design still provides for a roller sheath section respectively at the end of the roll in a tapered bearing and approximately in the middle by means of the circumference is stored distributed insulating body.
  • the roller table roller serves e.g. for transporting strip material from a treatment furnace exit or for transporting casting strands, e.g. from Thin strands.
  • the basic structure comprises a roller shell 1.
  • the at least at the roll ends 2 and 3 each electrically and / or thermally insulated is mounted on the roller shaft 4 (Fig. 1 and 1A as a first embodiment).
  • the insulation is created by the fact that between the roller shell 1 at the roll ends 2 and 3 and the roller shaft 4 distributed over the circumference arranged, individual Insulating body 5 (Fig. 1, 1A, Fig. 2, 2A and Fig. 3, 3A) are provided.

  • alternative can also be a one-piece, annular insulating body 6 (Fig. 4) is provided become.
  • the distributed over the circumference arranged, individual insulator 5 exist made of profiled bars 7, which are round, flat, rectangular or polygonal Possess cross-section.
  • the profile bars 2 are made of ceramic or other, with insulating effects associated materials.
  • the roller shaft 4 is equipped with Lürab accountsn 8 and 9 and is by means of Cooling media flowing through a core channel 10, cooled.
  • the profile bars 7 are axially secured together with bearing rings 11 and 12 on a shaft shoulder 13.
  • the axial securing consists of welded on the end faces 14 and 15 Sheet metal rings 17, each formed on the together with the profile bars 7 Bearings 16 are attached.
  • These bearings 16 may be used as a floating bearing 16a and a Fixed bearing 16b designed for thermal expansion.
  • the insulating body 5 center the roller shell 1 on the roller shaft 4 and form simultaneously by form and / or adhesion a torque transmission means.
  • the roller casing 1 is divided into several, spaced on the roller shaft 4 arranged roller shell sections 1a, 1b, 1c, 1d, etc., each again by means of the insulating body 5 to the roller shaft 4 center and transmit the drive torque.
  • the insulating body 5 is as Tapered bearing 18 is formed, either its cone inner ring 18a or its cone outer ring 18b and / or its tapered rollers 18c each have the insulating body 5 form.
  • the cone inner ring 18a is axial slidably and under spring force on the roller shaft 4 adjustable.
  • the cone inner ring 18 a is on the roller shaft 4 axially by means of disc springs 19 which against a Shaft paragraph 20 are supported, against the hollow, with the roller shell. 1 firmly connected cone outer ring 18b slidably.
  • the torque is at this design transmitted by frictional engagement in the cone outer ring 18b.
  • the Insulating material forms the conical outer ring 18b made of ceramic. Instead of ceramics can also fiberglass textiles with appropriate thickness or layering be used.
  • a roller shell section 1a, 1b, etc. can each at the roller ends 2 and / or 3 in the tapered bearing 18 and approximately centrally by means of the circumferentially distributed Insulator 5 are stored.
  • To prevent leakage currents over the surface of the insulating body 5 is to aim for a dry ambient atmosphere. Such is e.g. in the area of a treatment furnace.
