  • cooling medium is preferably applied to the surface of a cast or rolled stock, in particular a metal strip or sheet, or a roll.
  • DE 41 16 019 A1 relates to a device for cooling a metal strip with liquid nozzles arranged on both sides, which are designed as full jet nozzles. Impinging jets are formed by these nozzles, with areas of shooting flow forming around the impact point of the individual impact jets. In this device, the beams hit the belt surface freely and without any guidance or confinement.
  • a disadvantage of such a device for example, the relatively high water consumption and despite the efforts made difficult to avoid formation of a vapor layer between the firing flow and the surface to be cooled.
  • DE 27 51 013 A1 discloses a cooling device in which a spray of water containing spray is generated and directed to a metal plate to be cooled. The nozzles required for this purpose are designed as Venturi tubes, through which a targeted mixing of air and water is promoted. The resulting multiphase coolant flow leads to a vapor layer formation, which significantly affects the cooling effect.
  • JP 20051 18838 A discloses a device for cooling by spray nozzles. By using the spray nozzles, a jet of liquid and gaseous components is formed. This also forms a vapor layer on the material to be cooled, which precludes effective cooling.
  • the object of the invention is to provide an improved method for cooling foundry material, rolling stock or rolls.
  • the object is preferably to overcome at least one of the above-mentioned disadvantages.
  • the required amount of coolant should preferably be reduced or the efficiency, effectiveness and / or flexibility of the cooling should be improved.

  • a lower pressure negative pressure
  • a state is reached in which the nozzle on the surface to be cooled becomes saturated due to the pressure difference to the pressure in the vicinity of the nozzle.
  • the nozzle does not collide with the surface to be cooled, since the volume flow (permanent) is fed or tracked through the inlet of the nozzle.
  • a substantially constant distance between the Nozzle outlet and the surface to be cooled guaranteed. This distance is self-regulating or in other words, the distance adjusts itself.
  • variable or movable mounting of the nozzle at a distance from the surface may preferably be in a range between 0.1 mm and 5 mm, preferably between 0.5 mm and 2 mm.

  • the length of a cooling device can be reduced when cooling a tape in the direction of tape travel by the increased efficiency.

  • On the surface vaporizing cooling medium is shielded by the nozzle of the actual cooling zone.
  • the cooling performance of the nozzle is largely independent of the stray cooling medium. If multiple nozzles are distributed across a roller or belt width, portions of the roller or belt may either be less cooled or remain completely uncooled by shutting off nozzles in those areas.

  • the nozzle is biased in a direction perpendicular to the surface direction.
