Abstract

Un procédé de refroidissement de tôle laminée à chaud consiste à acheminer sur la surface de la tôle laminée (1) deux jets (6) d'un liquide de refroidissement orienté à un angle (α) sur la surface de ladite tôle (1), de manière à former entre eux une couche (9) de liquide de refroidissement produite par les jets envoyés par la tôle (1), ladite couche étant à l'état d'éblouissement pelliculaire, et une onde stationnaire étant produite dans l'interface liquide-vapeur. Simultanément, deux jets supplémentaires (7) de liquide de refroidissement sont acheminés, chacun d'eux étant orienté sur une partie de la couche (9) du liquide de refroidissement situé à proximité immédiate d'un des jets principaux (6).
