  • Publication number: 20060243357
    Abstract: The present invention relates to a cooling device for a quenching operation during the continuous annealing treatment of a flat product in the form of a metal strip (2), preferably a steel strip, said device: being located in an essentially vertical, ascending or descending path; comprising an overflow weir (4) in which a series of tubes (1) are completely immersed and stacked more or less vertically and symmetrically along each side of the strip (2) and which each eject onto the strip a cooling fluid in the form of essentially horizontal turbulent jets through a slit or a series of holes; being provided in its lower part with a sealing means (3); characterised in that any two successive tubes (1) located on a same side of the strip (2) are separated by a gap (B) that is identical for all tubes (1), chosen at a given value of specific flow rate of the cooling fluid, expressed in cubic metres per hour and per m2 of a surface of the strip so as to minimise the loss of flow in the evacuation passages corres
