Definitions

  • Casting machine with a device for application to a casting belt
  • the invention relates to a casting installation having a device for applying a fluid, in particular liquid metal, to a casting belt, in particular according to the preamble of claim 1.
  • the liquid steel from a reservoir is more or less continuously fed into the discharge chamber and from there via the device for applying substantially no large height difference on the cooled moving endless belt, which is usually a cooled metal strip.
  • the liquid metal is transported in casting speed and cooled and processed into a metal strip.
  • the liquid metal to be applied in the desired casting width and thickness is applied evenly and thinly to the moving belt, otherwise an uneven cast metal strip is produced.
  • this requires dispensing chambers of considerable width, with different dispensing chambers being required depending on the particular bandwidth.
  • the application can also take place in that the dispensing chamber has a smaller width than the width of the strip to be cast, wherein the liquid metal is expanded and distributed in the device for application to the desired G manbrei- te.
  • the object is achieved by a casting plant with a reservoir for a fluid, such as in particular for liquid metal, with a communicating via a connection with the reservoir output chamber, and with a device for applying, by means of which the fluid to the desired width is distributable, and by means of which it is distributable to a moving belt, wherein the connection between the discharge chamber and the device for applying is formed as a closed tubular connection.
  • a fluid such as in particular for liquid metal
  • the tubular connection is a closed tube.
  • the tubular connection comprises a plurality of closed tubes.
  • the closed tubes reduce the free surface area of the fluid. As a result, an increased level of thermal insulation is achieved so that the liquid metal does not cool down so much.
  • the plurality of closed tubes are arranged below and / or next to each other. It may be useful in a further embodiment, when the plurality of closed tubes is arranged parallel to each other. In a further embodiment, it is also expedient if the plurality of closed tubes is arranged like a fan to each other. This can be designed such that the tubes are closer to one another in the region of the end facing the dispensing chamber than at their opposite end. With regard to the outflow of the fluid, it is also advantageous if the end contour of the at least one tube is flattened and / or widened, so that an optimized outflow can take place.
  • the inlet of the tube for the fluid or the liquid metal in the region of the dispensing chamber during operation of the system is below the surface of the fluid or of the liquid metal in the dispensing chamber.
  • FIG. 1 is a schematic representation of a casting plant according to the invention with a device for applying a fluid, in particular liquid metal or liquid steel, to a casting belt,
  • Fig. 2 is a schematic representation of a device for applying
  • FIG. 3 shows a section through the device for applying according to FIG. 2.
  • FIG. 1 schematically shows a casting installation 1 according to the invention.
  • the casting installation 1 has a reservoir 2, in which preferably a fluid, such as liquid metal, 3 is produced, heated or liquefied or made available.
  • the liquid metal passes via the tube 4 into the dispensing chamber 5, from where it is distributed over a closed tube 6 to the device 7 for applying to the desired width 8 and is distributed to the moving metal strip 9.
  • the metal strip 9 is thereby moved as an endless belt around a pair of rollers 10, wherein only one of the rollers 10 is shown in FIG. The other roller is not visible.
  • the endless metal band 9 is wound around both rollers 10 and connected to a closed band.
  • the pipe 6 is designed to be closed, so that the free surface of the fluid is reduced.
  • the tube serves as heat insulation and the flowing through hot liquid metal 3 hardly cools off before it is expanded on the device for applying 7 and applied to the moving metal strip 9 and further cooled there. This results in a substantially uniformly formed cast metal strip 11.
  • the formation of the closed tube 6 as a connection between the discharge chamber 5 and the device 7 for applying the heat loss of the liquid flowing metal is reduced, since the free surfaces are reduced.
  • connection as a closed tube 6, as this can also save an inerting of the liquid metal 3 in the region of the closed tube 6, because apart from the device 7 for application, there are hardly any or no free surfaces, which would lead to a cooling or oxidation of the liquid metal.
  • the tube 6 with its inlet 12 in the region of the discharge chamber 5 below the Surface of the liquid metal is located so that the tube 6 is in operation below the level of the liquid metal.
  • surface waves that arise when the liquid metal enters the discharge chamber do not spread as much to the liquid metal in the tube, so that the casting process is substantially not affected thereby and the cast product is thereby also advantageous in terms of surface smoothness is affected.
  • tubes 6 which are arranged between the dispensing chamber 5 and the application device 7.
  • two or more tubes 6 may be arranged parallel next to and / or above one another.
  • tubes 6 may be provided, which are arranged expanded in approximately fan-shaped.
  • an outflow geometry of the final contour 13 which ensures a uniform outflow of the liquid metal. This can be achieved, for example, by flattening the tube 6 at the end at the end contour 13 and / or widening it in the plane of the device 7 for application.
  • the tube 6 may be formed as a heat-insulating tube 6, for example as a double-walled tube, so that the liquid metal, which flows through the pipe 6 maintains its temperature almost unimpaired and an unavoidable temperature reduction is advantageously minimal.
  • FIG. 2 shows a schematic representation of a device 20 for application, wherein FIG. 3 shows a relevant section.
  • the device 20 has a bottom 21 and two opposing side walls 22, 23.
  • the liquid metal flows from the pipe 6 coming from above the bottom 21 in the direction of the arrow R to the upstream wall 25, which is dimensioned in height such that it is lower than the two side walls 22,23.
  • the liquid metal then exceeds the wall 25 and drains between the wall 25 and the end wall 26 through an opening 27, so that the flow of the liquid metal is deflected substantially 90 ° downwards.
  • the end wall 26 is designed such that it is aligned substantially perpendicular to the flow direction of the liquid metal relative to the bottom 21.
  • the end wall 26 is preferably dimensioned to be substantially the same height as the two side walls 22, 23.
  • the side walls 22, 23 are advantageously designed such that they expand from the region 24, in which the liquid metal is applied to the device 20, in the direction of the two walls 25, 26 transversely to the propagation direction or flow direction R of the metal.
  • the lateral boundary of the expansion can be stepped or continuous.
