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 object is achieved by the features of claim 1.
  • the solution to the task is independent of Mold type, e.g. the vertical, vertical bend or circular mold.
  • the slag height (h slag ) mainly depends on the thickness of the mold inlet cross-section and the strand shell height (h strand shell ) on the lifting height of the oscillating mold.
  • Values for the hydraulic behavior, based on the 200 mm thick slab, are, for example, that of (FIG. 4) remove. It can be seen that larger mold thicknesses result in significantly more favorable hydraulic behavior to have.
  • an electromagnetic brake in the mold area can clearly show the turbulence in the mold area reduce.
  • the problems in maintaining the relation (1) are extraordinary elevated. That is, apart from the difficulty in supplying metal, it becomes almost impossible to rely on the Apply a small amount of mold powder to the small mold inlet cross-section to cover the enormous strand surface to lubricate and also set the relation (4).
  • the casting speed can be with a strand thickness of e.g. Increase 75 mm in the mold and thus in the bathroom mirror without any extra effort.
  • a continuous casting installation which contains all the features of the invention can be seen as an example from (FIG. 5).
