Definitions

  • the invention relates to a strip caster, in particular for the strip casting of steel.
  • the thickness of the finished roll can be reduced Hot strip (1 to 3 mm) as well as the required hot forming to achieve this sufficient material properties, the casting thickness of the strip is largely chosen optimally (e.g. approx. 10 mm).
  • Such a construction is technically very complex. It is also suitable for essential only for relatively small bandwidths. With larger bandwidths this is due to the thermal stress applied in the carrier much higher than that of narrow Bands, so that with large bandwidths, the construction acting as stiffening chain-like circumferential side boundary cannot be used.
  • the invention has for its object to provide a strip caster in which not only solidified steel adheres to the feed device and to the Side boundaries are reliably avoided, but also influence the potted Tape can be taken.
  • the vibrations of the feed devices and the side boundaries are formed perpendicular to the conveying direction of the belt.
  • the Vibration therefore takes place in the plane of the carrier tape or the potted one Steel belt, but across the conveying direction.
  • This has the advantage that the constructive Effort is less than with a vibration in the conveying direction, in which the Side boundary would have to be guided exactly over the entire length.
  • the vibration in the region of the metallurgical length is advantageous (from the casting area to the solidification of the belt) can be optimally adjusted by for example, the page boundaries in this area with individual sections each optimal frequency and amplitude can be divided.
  • the side boundaries can be set at an angle to each other. This refers to both the opposite page boundaries and the any existing sections of the respective page. This allows the potted tape improves the uniformity of the tape thickness over the entire width become.
  • the side boundaries are also opposite the vertical Carrier tape surface inclined.
  • the side wall boundaries consist of water-cooled hollow profiles.
  • the devices for generating the vibrations are preferably eccentric drives, however, electromagnets or hydraulic cylinders can also be used.
  • the Waveform can be sinusoidal, sawtooth-shaped or trapezoidal.
  • the stroke frequency is, for example, 50 Hz with a stroke of, for example, 0.5 mm.
  • the The cooling water is supplied via flexible hoses. With one preferred over the Potted tape is used to seal between the existing cover Side borders and the covers a layer of temperature-resistant Sealing material, in particular arranged from ceramic fiber felt.
  • a corresponding Sealing is provided between the feed device and the carrier tape, wherein preferably an aluminum sheet between the carrier tape and the seal is inserted so that only one relative movement between the vibration Felt layer and the aluminum sheet is done.
  • the feeder and the Side boundaries are preferably held by coil springs.
  • the limitations can both swing vertically and parallel to the belt movement (casting direction), so that overall gives a shear force also acting in the casting direction on the belt edge.
  • the vibration has components in all three spatial directions.
  • the vibration can take place perpendicular to the belt surface.
  • the vibrations are excited by blows in Longitudinal or transverse direction of the side boundary. This can suddenly Longitudinal waves are applied with which the adherence is effectively prevented can be.
