Abstract

PROCEDE ET DISPOSITIF POUR LE TRAITEMENT THERMIQUE DE PIECES DANS UN SYSTEME DE FOUR. IL COMPREND UN DISPOSITIF DE CARBURATION, UN FOUR DE REVENU, ET UN REFROIDISSEUR DE PIECES. LES COMPOSANTS DU FOUR SONT REALISES ET INTERCONNECTES DE SORTE QUE L'AIR DE COMBUSTION POUR LES DISPOSITIFS DE CHAUFFAGE A TUBE RAYONNANT APPORTANT L'ENERGIE THERMIQUE AUX PIECES DANS UN FOUR A HAUTE TEMPERATURE TEL QU'UN DISPOSITIF DE CARBURATION SOIT PRECHAUFFE PAR ECHANGE DE CHALEUR DANS UN REFROIDISSEUR DE PIECES ET PAR RECUPERATION DE L'ECHAPPEMENT DUDIT DISPOSITIF DE CARBURATION, LES PRODUITS DE COMBUSTION DE CELUI-CI RECHAUFFENT LES PIECES DANS LE FOUR DE REVENU; L'ECHAPPEMENT DE CE DERNIER FOUR EST UTILISE POUR PRECHAUFFER LES PIECES, ET L'ENERGIE TRANSFEREE PAR LES PIECES AU MILIEU DE TREMPE EST UTILISEE POUR CHAUFFER L'EAU DE LAVAGE DES PIECES. APPLICATION AU TRAITEMENT DE PIECES D'USINAGE EN METAL.
