Abstract

Pour diminuer de manière appropriée les vibrations d'une plaque d'acier en transfert, un dispositif électromagnétique de contrôle des vibrations est doté d'électroaimants agencés de manière à être tournés l'un vers l'autre, d'un détecteur prévu sur chaque électroaimant et qui détecte la distance entre chaque électroaimant et la plaque d'acier transférée entre les électroaimants tournés l'un vers l'autre, et d'une partie de commande qui commande le courant qui s'écoule vers chaque électroaimant en fonction de la distance qui est détectée par chaque détecteur entre la plaque d'acier et chaque électroaimant. Le dispositif électromagnétique de contrôle des vibrations assure un contrôle de manière à diminuer les vibrations de la plaque d'acier qui passe entre les électroaimants après que sa surface a été revêtue. Dans le dispositif, le gain de contrôle qui doit être utilisé pour contrôler le courant qui s'écoule vers l'électroaimant est déterminé sur la base de l'épaisseur, de la largeur et du type d'acier de la plaque d'acier.
