  • Incidents that occur during casting operation such as breakthroughs in a strand shell or overflows of the molten metal through the pouring opening of the mold usually lead to an interruption of the casting operation on the affected Mold.
  • parts of the continuous caster, especially the mold or parts of the mold and strand guiding devices below the mold of solidified metal can be freed or even replaced before the casting operation can be resumed.
  • Molds are usually held in a continuous caster by a holding device worn, which is designed so that the molds in a casting position can be oscillated.
  • the holding device is usually used as an oscillating table, which is accessible from above for the installation and removal of a mold.
  • molds with vertical or sloping Mold cavities become intermediate vessels in the casting operation above the molds arranged, from which molten metal is poured into the mold cavity , usually several molds with melt from an intermediate vessel be supplied with several spouts.

  • the movable sliding table requires open paths along the travel path in the Giessbühenêt Pits that are undesirable for safety reasons.
  • When using the Rotary tables in connection with multi-strand systems are large strand spacings and therefore large intermediate vessels are required.
  • An installation of this changing device in multi-strand systems not only leads to a high constructive Effort, but also too high operating costs, due to the maintenance the wear-prone intermediate vessels.
  • the holding device includes a platform on which the mold is attached in an operating position and their height with the help of two, provided with independent drives Lever systems is changeable.
