Definitions

  • the invention relates to a continuous casting mold for continuously casting a metal strand, in particular a steel strand, each having opposite broad side walls and narrow side walls, wherein at least the broad side walls are equipped with cooling channels.
  • Continuous casting molds are formed, for example, as slab molds, curved molds or Vorblockkokillen.
  • Continuous casting molds for continuous casting of a metal strand in particular a steel strand, are used as slab molds.
  • the molds have clamping walls that are opposite one another and are clampable between the wide side walls and narrow side walls that are displaceable along the width side transversely to the casting direction, tapered narrower in the casting direction or parallel to one another; the broad side walls have a funnel-shaped or parallel-walled pouring area. which extends in the casting direction to Kokillenende.
  • the broad sides of the mold can be arranged parallel to each other. In this case, the narrow side walls are interchangeably arranged according to the thickness of the metal strand to be cast.
