Title (EN) SYSTEM AND METHOD FOR TREATING AN AMORPHOUS ALLOY RIBBON
(FR) SYSTÈME ET PROCÉDÉ DE TRAITEMENT D'UN RUBAN D'ALLIAGE AMORPHE
Abstract:
(EN) A method and a system for continuously in-line annealing a forwarding ferromagnetic amorphous alloy ribbon in a curved shape to improve its magnetic properties without causing the ribbon to become brittle and which operates at significant high ribbon feeding rates. The amorphous alloy ribbon is fed forward, tensioned and guided along a path at a preset feeding rate and is heated at a point along the path at a rate greater than 103 oC/sec to a temperature to initiate a thermal treatment. Then the ribbon is initially cooled at a rate greater than 103 oC/sec until the thermal treatment ends. During the thermal treatment, a series of mechanical constraints is applied on the ribbon until the amorphous alloy ribbon adopts a specific shape at rest after the thermal treatment is ended. After the initial cooling, the amorphous alloy ribbon is subsequently cooled at a sufficient rate to a temperature that will preserve the specific shape.
(FR) Cette invention concerne un procédé et un système de recuit continu en ligne d'un ruban d'alliage ferromagnétique amorphe se déplaçant dans un sens d'avance. Une forme incurvée est donnée audit ruban afin d'améliorer ses propriétés magnétiques sans le rendre cassant. Ledit procédé opère à des vitesses d'alimentation du ruban significativement grandes. Le ruban d'alliage amorphe est acheminé en avant, tendu et guidé le long d'un trajet à une vitesse d'alimentation prédéterminée. Ledit ruban est chauffé en un point du trajet à une vitesse supérieure à 103 °C/sec jusqu'à une certaine température pour initier un traitement thermique. Ensuite, le ruban est initialement refroidi à une vitesse supérieure à 103 °C/sec jusqu'à la fin du traitement thermique. Pendant le traitement thermique, une série de contraintes mécaniques est appliquée sur le ruban jusqu'à ce que le ruban d'alliage amorphe adopte une forme spécifique au repos après la fin du traitement thermique. Suite au refroidissement initial, le ruban d'alliage amorphe est refroidi à une vitesse suffisante à une température qui va préserver la forme spécifique.
