Definitions

  • Fluid outlet rows can be arranged equidistantly or with varying spacing. Orifices can also be installed inside the fluid chamber to ensure that an almost identical amount of cooling fluid is applied to a flat product to be cooled per fluid outlet, despite changing pressure distributions in the cooling beam.
  • the varying device arranged partially or completely within the fluid chamber can be set up to vary the length of the at least one fluid outlet row at one end region or at both end regions of the fluid chamber.
  • the varying device can have at least one shielding means, which is movably arranged within the fluid chamber, for closing or covering fluid outlets and at least one actuator, which is drivingly connected to the shielding means, for actuating the shielding means.
  • the varying device of the respective cooling bar 13 can be set up to reduce the length of the fluid outlet row of the cooling bar 13 at at least one end region of the fluid chamber by up to 40%.
  • the device 4 has control and / or regulating electronics 14 connected to the supply device and the varying device, which are set up to control the supply device and the varying device in such a way that when a reduced row of fluid outlets of the respective cooling bar 13 is present, a flow from the fluid outlets of the reduced Fluid outlet row exiting volume flow of the cooling fluid compared to a volume flow of the cooling fluid emerging from the respective fluid outlet of the maximum fluid outlet row when there is a maximum fluid outlet row of the cooling bar 13 is increased by a cooling fluid volume flow which corresponds to at least a part of a volume flow of the cooling fluid that corresponds to that in the presence of the maximum fluid outlet row from the Exits fluid outlets of the maximum fluid outlet row, which are closed by means of the varying device when the reduced fluid outlet row is present.

Abstract

L'invention concerne un dispositif (4) destiné à refroidir séquentiellement des produits larges plats (3) métalliques, comprenant au moins une poutre froide (13) et un équipement d'alimentation destiné à alimenter la poutre froide (13) en un fluide réfrigérant, la poutre froide (13) comportant une chambre de fluide, au moins une rangée d'évacuations de fluide s'étendant le long d'un axe longitudinal de la chambre de fluide et au moins un équipement de variation agencé au moins partiellement à l'intérieur de la chambre de fluide destiné à faire varier une longueur de la rangée d'évacuations de fluide au niveau d'au moins une zone d'extrémité de la chambre de fluide. Le dispositif (4) comporte au moins une électronique de commande et/ou de réglage (14) connectée à l'équipement d'alimentation et à l'équipement de variation, qui sert à commander l'équipement d'alimentation et l'équipement de variation de telle sorte qu'un flux volumique du fluide réfrigérant sortant des évacuations de fluide de la rangée d'évacuations de fluide réduite lorsqu'une rangée d'évacuations de fluide réduite est présente est renforcé, par rapport à un flux volumique du fluide réfrigérant sortant de l'évacuation de fluide respective de la rangée d'évacuations de fluide maximale lorsqu'une rangée d'évacuations de fluide maximale est présente, d'un flux volumique de fluide réfrigérant qui correspond à au moins une partie d'un flux volumique du fluide réfrigérant qui sort des évacuations de fluide respectives de la rangée d'évacuations de fluide maximale, lorsque la rangée d'évacuations de fluide maximale est présente, qui sont fermées au moyen de l'équipement de variation lorsque la rangée d'évacuations de fluide réduite est présente.
