Abstract

L'invention concerne un procédé et un appareil de recuit d'acier au silicium. Des charges individuelles S d'acier au silicium sont transmises à un four tunnel 6 ayant des vestibules 4 et 8 de chargement et de déchargement. Le recuit est réalisé en atmosphère d'hydrogène, et les vestibules sont purgés à l'azote puis à l'hydrogène. L'hydrogène utilisé pour la purge est prélevé dans l'atmosphère de recuit, et de l'hydrogène neuf est ajouté dans cette atmosphère afin que la pression reste constante. Application au recuit de l'acier.
