  • the central component of a two-roll caster is of two counter-rotating Casting rolls with parallel arranged casting roll axes and two at the formed opposite end faces of the casting rolls adjacent side plates.
  • the distance between the two Gellowalzenachsen each other is adjusted so that the lateral surfaces the casting rolls form a substantially parallel casting gap, the casting thickness of the casting metal strip corresponds to the lateral surfaces of the cooperating casting rolls and the two end faces of the side plates form a circumferentially closed Space for holding the molten metal, which is fed via an inflow, to the cooled shell surfaces of the casting rolls solidified and in the form of at least a large extent fürerstarrten metal strip is discharged from the casting gap.
  • a plant of this Type and function is already known for example from WO 98/04369

  • the on The end faces of the casting rolls adjacent side plates are made of refractory Material and are embedded in a support frame, the part of a soplattenmanipulators or a supporting and supporting device for the side plates is such devices are in many Ausunsngsformen, such as from EP-A 714 715 or EP-B 620,061 known
  • the side panels made of refractory material are against the front sides of the Casting rollers pressed with predetermined pressure to a close concern to this To ensure end faces.
  • the side panels are tall and locally different exposed to mechanical and thermal loads. In the melting pool and in the area of the G confusespaltes there is a direct contact with the Metattschmetze and thus considerable thermal or chemical wear; in the area of the contact surface of Side plates and end faces of the casting rolls are predominantly more mechanical Wear by the relative movement of the components under pressure and elevated temperature.
  • WO 98/04369 To minimize the overall wear and increase the life of the side plates are already known solutions in which the side plates according to the local stresses are made of different materials.
  • the prior art side plates will bear against the casting roll surface pressed or continuously moved toward the casting roll shell surface.

Furthermore, the horizontal wear of the side plates at the contact surface with the casting-roll ends are reduced as well as the wear in the contact surface of the side plates with the solidified band shells and at the same time achieves a better strip edge quality when exiting the casting gap become.
  • This object is achieved in a method of the generic type characterized that the side plates in a first time interval in a first direction of movement be moved parallel to the G monwalzenachsen against the end faces of the casting rolls and that the side plates in a second time interval in a second Direction of movement parallel to the casting direction in the casting gap against a portion of The lateral surfaces of the casting rolls are moved.
  • both sealing surfaces are continuous or in Renewed time intervals.
  • the first time interval begins before the second Time interval.
  • an advancing movement of the side plates in the direction of G confusewalzenachsen takes place and so a grinding of the side plates on the front sides of the Casting takes place and only delayed by a vertical movement in the casting direction a grinding of the side plates on the lateral surface of the casting rolls to an extent takes place, which the respective wear by the movement of the side plates in the direction of G confusewalzenachsen corresponds.
  • the first time interval begins with the feeding of the molten metal into the melting space or before.
  • a certain amount of time advance allows the bridging of production or mounting-related inclinations of the side plates as well as production or thermal conditional deformations of the side plates and the resulting gaps between Casting rollers and side plates through the grinding process.
  • the materials for the side plates must have high thermal endurance, high thermal shock resistance, high abrasion resistance on contact with molten metal and casting surface, resistance to chemical erosion and corrosion.

  • the enclosed in the side plates sealing surfaces are during the current Casting gradually damaged and degraded by erosion and corrosion, so it sufficient for the production of a perfect metal strip when the side plates be moved intermittently during the second time interval, with movement phases and stoppage phases alternate and the stoppage phases of the side plates 30 min, preferably 5 min, not exceed.
