  • the reflection losses occurring here at an acute angle are substantially lower than in the case of a vertical impact, and therefore the expansion of the coolant counter to the running direction on the surface of the metal strip, ie the effective cooling length, is considerably greater than in the prior art.
  • the inventively formed turbulent flow field in the cavity opposite to the direction of travel is much longer / deeper than in the prior art, whereby a much better heat transfer is achieved and more heat can be removed from the metal strip.
