Abstract (en)
Cooling of a metal band on a treatment line uses cooling zones having containers filled with a cooling gas. Each zone progressively modifies the intensity of cooling. An Independent claim is included for an apparatus for performing the above where the band passing the containers while moving between inlet and outlet rollers. A treatment zone is located between adjacent containers, between the inlet roller and the first container and the last container and the outlet roller. Preferred Features: The distance between gas outlets in the containers is variable. The distance of the outlets from the band is adjustable. The size of the orifices is adjustable.
Abstract (fr)
Procédé de réduction de la formation de plis sur des bandes métalliques soumises à un refroidissement dans des lignes continues de traitement thermique dans lesquelles lesdites bandes sont amenées à traverser des zones de refroidissement comportant des caissons munis de moyens de soufflage d'un gaz de refroidissement caractérisé en ce qu'il consiste à modifier progressivement l'intensité du refroidissement à chaque variation de la pente du cycle de refroidissement.
