Definitions

  • the invention relates to a method and an apparatus for Reduction of heat dissipation of a continuous casting mold, especially in their bathroom mirror area.
  • the invention has for its object a means for Reduction of the heat dissipation of a continuous casting mold specify that preferably acts in the bathroom mirror area and can be attached or replaced with little effort.
  • the task is solved in that the heat flow between the strand shell that forms and the inner surface of the mold by increasing the thermal resistance as a result effectively roughening the mold surface and is equalized at the same time. That way reduced heat dissipation in the area of the bathroom mirror leads to the fact that the strand shell that forms remains thin longer and of that increasing with increasing distance from the bathroom mirror ferrostatic pressure more evenly on the copper plate of the Continuous casting mold is pressed.
  • the conversion of the Deltain the gamma phase occurs later, so that's it associated shrinkage of the strand shell has less impact.
  • the more even heat transfer also occurs in the Strand shell lower tensions due to temperature differences on. In this way, the formation of cracks in the Strand shell prevented.
  • the reduced heat flow density between the formed Strand shell and the inner surface of the mold are the result of a corresponding macro structure of this inner surface.
  • Their targeted roughness has a certain depth and structure on.
  • An advantageous embodiment of the invention is that the macrostructure of the inner mold surface by itself known processes such as Shot Blast Texturing (SBT), Electric Discharge Texturing (EDT), Electron Beam Texturing (EBT), Laser Texturing (LT) or through a perforated texture (GLT) or is realized by other methods.
  • This Roughening processes are known per se and have u. a. to the Roughening work rolls for re-rolling Body panels proven.
  • the rough mold inner surface has if the mold is lubricated with casting powder, the additional one Advantage that the slag of the casting powder more intensely on the Mold inner wall adheres. This reduces the risk detachment of the entire slag layer over larger ones Surfaces. This would have caused a sudden change in local Strand shell temperature with strong temperature voltages soeir increased friction between the strand shell and the mold Episode.
  • the fact that the surface texture covers only part of the Mold width is arranged can be different Surface temperatures in the direction of the mold width be balanced.
  • Another advantage of the solution according to the invention is in that the macrostructure on an inner mold surface also retrospectively or, if worn, as a repair solution can be attached. If the inner surface of the mold is in front of or after their macroscopic processing with a Wear protection layer is provided, the wear of the Macro structure diminishes and thereby the lifespan of the Continuous casting mold increased.
  • the inventive design of the inner surface of the Continuous casting mold (K) is reduced by throttling the Heat flow in the area of the bathroom mirror the quality of the Cast strand increases and the formation of cracks thereof avoided.
