Definitions

  • the invention relates to a casting device with a ladle, a distributor and a horizontal movable conveyor belt with side boundaries according to the preamble of claim 1 and a method for operating a casting apparatus according to the preamble of claim 2.
  • Such devices for horizontal casting have the disadvantage that they are defined in their width and it requires a significant conversion of the system to change the casting width, or the width of the Vorbandes, if such a conversion is even economically reasonable. For this typically very extensive disassembly and assembly steps are necessary and expensive components are needed, so that such changes to a plant in the broad offer rather little. Accordingly, different horizontal casting plants are also constructed for different casting widths, which can then be utilized to their capacity,

  • the distribution device is viewed in width in the direction of the width of the conveyor belt adjustable.
  • At least one cooling device is arranged, which serves to run on the conveyor belt with casting speed Metal to be cooled, wherein the at least one cooling device in the width in the direction of the width of the conveyor belt is variably controllable, such that the at least one cooling device viewed in width in the direction of the width of the conveyor belt is divisible into cooling zones, wherein at least two edge zones are present, which can be switched on or off depending on the width to be cooled. Furthermore, a nertgaschaube is provided above the conveyor belt to protect the Vorbandes.
  • the pre-strip can be generated variably in width.

  • the horizontal conveyor belt 5 is a driven conveyor belt, which removes the solidified on the moving conveyor belt metal, such as the pre-strip 7, with casting speed.
  • rollers 6 are provided, around which the driven conveyor belt 5 rotates as an endless belt.
  • cooling devices 9 are preferably arranged below the conveyor belt 5 and / or also above the conveyor belt, which serve to be controlled on the conveyor belt 5 with casting speed solidified Vorband 7 and to cool down specifically.
  • the cooling devices 9 are, for example, spray devices spraying coolant, from which a coolant, for example water, is sprayed or applied onto the conveyor belt and / or onto the pre-strip.
  • a coolant for example water
  • the heat-conducting conveyor belt 5 can be cooled as such itself, so that the solidified metal applied on the conveyor belt 5 is cooled as a pre-strip 7.
  • the heat of the Vorbandes 7 is transported by the sprayed or sprayed coolant, such as cooling water, from the opening band.
  • an inert gas hood 8 is provided, which protects the Vorband from the external air atmosphere.
  • the inert gas hood 8 may well rest on the two side boundaries 13, 14 in order to avoid heat losses.

  • the width of the distributor 12 at the outlet of the distributor 12 is in the FIGS. 2 and 3 unchanged.
  • the distribution device 12 has a width that is greater than the distance between the two side boundaries 13,14.
  • the device of FIG. 4 thus represents one Arrangement for a low bandwidth.
