Abstract:
1. A device for acting on the temperature of a travelling strip, the device comprising: at least two blowing modules arranged opposite one another on either side of a zone of travel of the strip, each blowing module consisting of a plurality of tubular nozzles extending from at least one distribution chamber in the direction of the zone of travel of the strip, the nozzles being arranged in such a way that the impacts of jets from the tubular nozzles on each face of the strip are distributed at the nodes of a two-dimensional network, wherein, in order to reduce the vibrations of the strip which are induced by the blowing of gas or a gas/water mixture, the heads of the tubular nozzles extend at a distance from the distribution chamber in such a way as to leave a free space for the flow of the returning gas or water/gas mixture parallel to the longitudinal direction of the strip and perpendicular to the longitudinal direction of the strip, and the blowing modules are set in such a way that the jet impacts on one face of the strip are not opposite the jet impacts on the other face of the strip.
