Abstract

Four de traitement thermique de pièces comprenant une enveloppe isolée qui comporte un passage obturable de chargement et de déchargement donnant sur l'espace destiné à loger la charge et pouvant être chauffé sous atmosphère contrôlée, formée d'un gaz de protection. Un dispositif de refroidissement 17, 18 du gaz de protection est raccordé au four. Application très avantageuse en particulier aux fours à chambre pour traitement de revenu afin de permettre de contrôler et d'accélérer le refroidissement des pièces.
