A method and means for soft cooling a moving heated metal strip comprises forming a descending waterwall extending across the metal strip in a direction perpendicularly to the line of travel of the strip. Air jets, variable in angle to the vertical direction of the descending waterwall, impact the waterwall, converting it to a descending curtain of air-water mist which impinges upon an upper surface of the metal strip to effect soft cooling of the strip.
Méthode et équipement destinés au refroidissement lent d'une bande métallique chauffée mobile comprenant un mur d'eau descendant, disposé en travers de la bande métallique, perpendiculairement à la direction de déplacement de cette dernière. Des jets d'air, à angles variables par rapport à la direction verticale du mur d'eau descendant, frappent le mur d'eau et le transforment en un rideau de bruine et d'air descendant, qui se précipite sur la surface supérieure de la bande métallique et la refroidit lentement.
