Definitions

  • the invention relates to a continuous casting plant with a in the area of the continuous casting mold trained magnetic field with in the preamble of the independent claim specified features.
  • An electromagnetic brake known from EP-A-317 790 type mentioned is designed so that several electromagnets by a circumferential yoke connected to each other, arranged around a continuous casting mold are.
  • the invention is therefore based on the object in a generic Continuous caster to improve the calming of the steel bath and the turbulence to decrease further in the steel bath.
  • each magnet has a central core from the magnets used, the mold side in at least one upper core for an upper magnetic field and divides a lower core for a lower magnetic field, whereby an im Operation arising magnetic field with respect to the continuous casting mold in at least an upper and a lower magnetic field is divided.
  • the upper magnetic field is used primarily for smoothing the bathroom mirror while the lower magnetic field primarily slows down the incoming steel. Because of the invention Division into an upper and a lower magnetic field without change the sign of the poles, this results in particular for wide molds simpler construction of the magnetic device.
  • this magnetic field can extend over at least two levels generated both by permanent magnets and by electromagnets be, which are preferably attached to the mold.
  • This stationary Magnets oscillate with the mold or the lifting table.
  • Each magnet can advantageously be attached to the mold by the in the area the water box of the mold arranged magnets over their upper and lower cores, in particular, screwed to the copper plates assigned to the mold are.
  • An expedient embodiment of the invention provides that by means of a on the continuous casting mold height adjustable magnets the effect on the Steel bath, especially the braking effect can be changed.
  • the effect of Magnetic fields on the steel bath due to a variable distance be influenced between each upper and lower core. This measure is particularly suitable in connection with the height adjustment of the magnets according to claim 4.
  • FIG. 1 shows in a schematic Way and in cross section with a continuous casting mold associated magnetic field generator.
  • Lifting die arranged continuous casting mold 1 consists of the Broad sides of the mold 1 attached copper plates 2, 3 which are attached to the magnets, which are denoted overall by 4, 5 are. Above and below the magnets 4 and 5 are the Water boxes 6, 7 recognizable.
  • the magnets 4, 5 shown in the exemplary embodiment act electromagnets, which are inherently non-magnetic Central core 8, 9 from the magnetic field one surrounding coil 11, 12 is penetrated.
  • the entire magnet, consisting of central cores 8, 9, lower cores 13, 14, upper cores 15, 16 and the circumferential Yoke 17 is in relation to the continuous casting mold 1 in Height adjustable in the direction of arrow 18. Depending on the setting there is a different effect of the magnetic fields on the incoming steel.
