Method and plant for cooling a moving metal strip

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...

Zusammenfassung:	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, and the heat transmitted from the strip ( 2 ) to the support roller ( 14 ) is discharged using secondary cooling means ( 16 ).
