  • the ingots are arranged horizontally movable on ingot holding means in the ingot chamber.
  • DE 10 2014 100 976 A1 discloses a continuous casting apparatus and a pseudo-continuous process for the production of ingots, which, however, brings a number of disadvantages.
  • the ingot is clamped by means of clamping devices (55A, 55B) in order to fix the ingot in a separating device. All this makes the device as a whole complex and affects the surface quality of the ingot through the contact of the ingot surface with the material of rollers and clamping device.
  • DE 10 2014 100 976 A1 discloses a device in which the stoppage of the casting process is not determined by the cooling of the cast ingot, but by the separation of the cast ingot from the subsequent ingot and required gas exchange times of the discharge chamber.
  • this increase in throughput comes at the price of inherent problems due to a complex plant design.
  • DE 1 558 248 A describes a device for forwarding cut-off cast blocks during continuous metal casting. There, after cooling, the resulting ingots are placed on a cart and taken away.
