Abstract
UN PROCEDE POUR FOURNIR CONTINUELLEMENT DU FER POUR LE COULAGE DE FER A GRAPHITE COMPACT (FGC), COMPRENANT LES ETAPES DE PRODUCTION DE FER FONDU, L'INTRODUCTION D'AGENTS POUR REGLER LE POTENTIEL DE GRAPHITISATION ET, SI NECESSAIRE, DESULFURISER LE FER FONDU EN UN CONTENU EN SOUFRE INFERIEUR A 0.025 %, TRANSFERER LE FER FONDU DANS UN FOUR DE CONDITIONNEMENT DANS LEQUEL LA QUANTITE DE FER FONDU EST MAINTENUE DANS LES LIMITES PREDETERMINEES EN REMPLACANT LE FER TIRE DU FOUR AVEC UNE QUANTITE DE COMPENSATION EN FER FONDU, VERSER LE FER FONDU DANS DES MOULES OU DES POCHES PUIS DANS LES MOULES ET AJOUTER DES AGENTS D'INOCULATION ET DES MODIFICATEURS GRAPHIQUES. UN ECHANTILLON DE FER FONDU EST PRIS AVANT LE VERSEMENT OU APRES, DANS LES MOULES. L'ECHANTILLON EST LAISSE POUR SE SOLIDIFIER EN UN ETAT OU ECHANTILLON ET SON RECIPIENT ONT UN EQUILIBRE THERMIQUE A UNE TEMPERATURE AU DESSUS DE LA TEMPERATURE DE CRISTALLISATION TOUT EN ENREGISTRANT LE CHANGEMENT DE TEMPERATURE DU FER EN FONCTION DU TEMPS AU CENTRE DE L'ECHANTILLON ET A PROXIMITE DE LA PAROI DU RECIPIENT. ON UTILISE LES CHANGEMENTS DE TEMPERATURE POUR ETABLIR LES PROPRIETES STRUCTURELLES ET LE POTENTIEL DE GRAPHITISATION DU FER EN UNE MANIERE CONNUE ET LORSQUE LEDIT POTENTIEL ET LES DITES PROPRIETES DU FER DE FONTE S'ECARTENT DES PROPRIETES CONNUS DU FGC, ON AJUSTE LA QUANTITE DE L'AGENT AJOUTE POUR REGLER LE POTENTIEL DE GRAPHITISATION OU LA QUANTITE DE MODIFICATEUR GRAPHITIQUE AJOUTEE OU RETIREE, OU LA QUANTITE D'AGENT D'INOCULATION AJOUTEE ET CE EN RELATION AVEC LEDIT ECART
