Abstract

L'invention concerne un procédé et une machine pour le traitement des chaînes à maillons. Dans le procédé selon l'invention, on procède à la trempe et au revenu par passage continu de la chaîne 27 dans deux fours à induction 2 suivis de dispositifs réfrigérants 5. On agit sur la vitesse de la chaîne ou la puissance du four de façon à ce que les parties courbes de chaque maillon bénéficient d'une température de trempe plus élevée et/ou d'une température de revenu plus basse que les parties droites des maillons. Le procédé selon l'invention convient en particulier pour le traitement thermique des chaînes utilisées pour les appareils de levage, les transporteurs à chaînes, les élingues et autres.
