摘要

Process improvement of cooling of a cooling gas chamber inflated or a section of cooling air blown from a line of heat treatment of steel or alumu00ecnio and / or improvement of the quality of the products to treat by reduction of variations generated by this resf Riamento and device implementing the process.The invention relates to a process and a device for improving the cooling chamber and a cooling gas inflated or a section of the cooling air inflated and / or improvement of the quality of the products to treat, in which protrudes jets of gas or air in the direction of each One side of the strip on displacement in the chamber or section.According to the invention, jets of gas or air (58) are emitted from the tube insufflation (52) fitted to the tubular nozzle (51) arranged away from each other transversely to the direction (100) of displacement of the strip (53).The so-called jets being directed to the face concerned of the strip being for this inclined essentially at the same time to the edges of the strip in a plane perpendicular to the plane of the strip and in the direction (100) of displacement of said strip, and upstream or downstream of the strip in a plan perpend Icular to the plane of the strip and parallel to the direction (100) of displacement of said strip.
