| 摘要 |
The invention relates to a method for acting on the temperature of a running strip (4), by blowing a gas or a water-gas mixture, wherein said method comprises ejecting, on each surface of the strip, a plurality of jets of said gas or water-gas mixture extending towards the surface of the strip and arranged such that the impacts (24, 34) of the jets of said gas or water-gas mixture on each surface of the strip are distributed at the nodes of a two-dimensional network. The impacts (24) of the jets on a surface (A) are not directly opposite the impacts (34) of the jets on the other surface (B), and the jets of said gas or water-gas mixture are generated by tubular nozzles (22, 23) supplied by at least one distribution casing (21, 31) and extending at a distance from the distribution casing in order to leave a free gap for the flow of the returning gas or water-gas mixture, in parallel to the longitudinal direction of the strip and perpendicularly to the longitudinal direction of the strip. |
