Abstract

In order to cool a metal strip (2) which moves in a continuous manner:the strip (2) is pressed onto a main cooling roller (10) so that the strip forms an arc whose inner face delimits, with the outer face of this roller, a contact zone which is suitable for discharging part of the heat of the strip towards the inner side of the roller,the strip (2) is held in contact with the main cooling roller (10) by means of a support roller (14) on the outer face of the strip, which roller is constituted by a resiliently deformable and thermo-capacitive material, andthe heat transmitted from the strip (2) to the support roller (14) is discharged using secondary cooling means (16).
