Abstract

Four d'égalisation de température chauffé inductivement pour des pieces métalliques de conductibilité thermique faible préchauffées au défilé. Ce four comporte un tube chauffant 4 entouré par une bobine d'induction 6 avec interposition d'un matériau isolant thermique 5, réalisé en un métal réfractaire et présentant une épaisseur de paroi d'au moins 12 mm, un dispositif de mesure 24 de la température du tube chauffant 4, un dispositif de régulation de température accouplé à ce dispositif de mesure et un écran thermique amovible 22 disposé à l'ouverture de sortie du four. Application : fours de traitement thermique.Inductively heated temperature equalization furnace for metal parts of low thermal conductivity preheated in the process. This furnace comprises a heating tube 4 surrounded by an induction coil 6 with the interposition of a thermal insulating material 5, made of a refractory metal and having a wall thickness of at least 12 mm, a measuring device 24 of the temperature of the heating tube 4, a temperature control device coupled to this measuring device and a removable heat shield 22 placed at the outlet opening of the oven. Application: heat treatment furnaces.
