Definitions

  • the invention relates to a continuous caster and a method for producing thin slabs.
  • the object of the invention is to provide a method which makes it possible to to achieve the predetermined thickness of the thin strand in such a way that optimal conditions for the supply of slag as well as in the reduction of the strand thickness in the mold and in the guide stand during casting rolling.
  • the slag height h slag mainly depends on the thickness of the mold inlet cross section and the strand shell height h strand shell depends on the lifting height of the oscillating mold.
  • the constant thickness leads to a constant formation of slag over the width of the mold level and thus to one constant slag supply in the area of the meniscus of the entire continuously forming strand shell (3).
  • This constant. Slag formation from casting powder or granules (5) over the casting width avoids the Danger of insufficient lubrication between the immersion nozzle and the copper broad side plates. This danger exists since the pouring slag has a glassy structure (silicate structure) with a viscous behavior of approx. 0.5-10 poise.
  • an electromagnetic brake in the mold area can clearly show the turbulence in the mold area reduce.
