Title
(EN)
ROTATING MAGNET HEAT INDUCTION
(FR)
INDUCTION DE CHALEUR PAR AIMANTS ROTATIFS
Abstract:
(EN)
A rotating magnet heater for metal products, such as aluminum strip, can include permanent magnet rotors arranged above and below a moving metal strip to induce moving or time varying magnetic fields through the metal strip. The changing magnetic fields can create currents (e.g., eddy currents) within the metal strip, thus heating the metal strip. A magnetic rotor set can include a pair of matched magnetic rotors on opposite sides of a metal strip that rotate at the same speed. Each magnetic rotor of a set can be positioned equidistance from the metal strip to avoid pulling the metal strip away from the passline. A downstream magnetic rotor set can be used in close proximity to an upstream magnetic rotor set to offset tension induced by the upstream magnetic rotor set.
(FR)
L'invention concerne un dispositif de chauffage à aimants rotatifs utilisé sur des produits métalliques, tels qu’une bande d’aluminium, qui peut comprendre des rotors à aimants permanents disposés au-dessus et au-dessous d’une bande métallique mobile pour induire des champs magnétiques mobiles ou variant dans le temps à travers la bande métallique. Les champs magnétiques variables peuvent créer des courants (par exemple, des courants de Foucault) à l’intérieur de la bande métallique, ce qui permet de chauffer la bande métallique. Un ensemble de rotors magnétiques peut comprendre une paire de rotors magnétiques appariés situés sur des côtés opposés d’une bande métallique, qui tournent à la même vitesse. Chaque rotor magnétique d’un ensemble peut être positionné à équidistance de la bande métallique pour éviter d’arracher la bande métallique de la ligne de passage. Un ensemble de rotors magnétiques aval peut être utilisé à proximité immédiate d’un ensemble de rotors magnétiques amont pour décaler la tension induite par l’ensemble de rotors magnétiques amont.
