Abstract

The invention concerns a method for cooling metal strips using cooling chambers by blowing a gas, in a continuous heat treatment line, wherein: the chambers (4,4a...4', 4'a...) have a unitary dimension (h) in the moving direction (X) of the strip less than two meters and are split along the direction perpendicular to the moving direction (X) of the strip into a plurality of unitary blowing sectors; each unitary blowing sector is equipped with at least one blowing pressure sensor (7) and with at least one actuator (2) for adjusting the pressure of each of said unitary sectors; and a controlling and regulating system controls the actuators (2) such that the longitudinal theoretical distribution of pressure in the blowing sectors corresponding to a cooling curve of the target strip is adapted so as to take into account a modification of the position of the strip relative to the blowing sectors to avoid any contact thereof with the walls of the devices of the cooling zone without modifying the cooling curve.
