Wind tunnel having a free jet test section for simulating wind direction

A device for removing liquid from the surface of a moving strip (B), more particularly a rolled strip on a roll stand, by means of a gas, more particularly air, blown on to the moving strip (B), is characterized according to the invention in that disposed transversely of the direction (L) in which the strip runs is a slot nozzle (3) which is directed at the strip surface at an angle (.beta.) of 45.degree. to 90.degree. of its jet oppositely to the direction (L) in which the strip runs, the ratio between the distance (h) of the slot nozzle (3) from the moving strip (B) and the width (s) of the slot is in the range h/s=2 to h/s=10, so that the velocity of emergence of the gas jet blown by the slot nozzle (3) on to the strip (B) is in the range of 0.3&lt;Mach&lt;2, and a suctional removal gap (4) is disposed above the strip (B) at a distance of 5 to 25 nozzle distances (h) in the direction (L) in which the strip (B) runs upstream of the line of impingement of the gas jet emerging from the slot nozzle (3).

The invention relates to a device for cooling a laminar material, more particularly a metal strip 2, by liquid nozzles 11a, 11b, 12a, 12b disposed on both sides. The liquid nozzles 11a, 11b, 12a, 12b take the form of full-jet nozzles and so act upon the surface of the material 2 to be cooled by rebounding jets that zones of shooting flow SS are formed around the point of impingement of the individual rebounding jets.
