PRE-COOLING SYSTEM HAVING CONTROLLED INTERNAL ADJUSTMENT

The invention relates to equipment for cooling a metal strip (2) having a liquid coating to be solidified, wherein said strip is continuously moving. Said equipment is characterized in that each half-cooler (11, 12) is divided, over the length thereof, into at least two sections, a first section (13...

Beschreibung
Zusammenfassung:	The invention relates to equipment for cooling a metal strip (2) having a liquid coating to be solidified, wherein said strip is continuously moving. Said equipment is characterized in that each half-cooler (11, 12) is divided, over the length thereof, into at least two sections, a first section (13) and a second section (14), in the direction of the movement of the strip (2). The first section (13) is separated from the second section (14) in each half-cooler (11, 12) by a respective internal adjustment device (7, 8), making it possible to change the gas flow/pressure parameter so that the value of said gas flow/pressure parameter is different in the first section (13) from the value of said parameter in the second section (14). Installation pour le refroidissement d'une bande métallique (2) présentant un revêtement liquide à solidifier, ladite bande étant en défilement continu, caractérisée en ce que chaque demi-refroidisseur (11, 12) est divisé sur sa longueur en au moins deux sections, une première section (13) et une deuxième section (14), selon le sens de défilement de la bande (2), la première section (13) étant séparée de la deuxième section (14) dans chaque demi-refroidisseur (11, 12) par un dispositif de régulation interne respectif (7, 8) permettant de modifier le paramètre débit/pression de gaz de sorte que la valeur dudit paramètre débit/pression de gaz soit différente dans la première section (13) par rapport à sa valeur dans la deuxième section (14).
