The invention relates to a method of quenching a steel load by flowing a gas around the load using a gas drive means. The gas drive means is controlled such that the gas flows around the load at a velocity that varies according to the velocity profile, at least one part of which comprises, successively, one stage at a first velocity (44) and one stage at a second velocity (46) which is greater than the first.
L'invention concerne un procédé de trempe d'une charge en acier par écoulement d'un gaz au niveau de la charge par l'intermédiaire d'un moyen d'entraînement du gaz. Le moyen d'entraînement est commandé pour faire s'écouler le gaz au niveau de la charge à une vitesse qui varie selon un profil de vitesses dont au moins une partie comprend, successivement, un palier à une première vitesse (44) et un palier à une seconde vitesse (46) supérieure à la première vitesse.
