Abstract

L'INVENTION CONCERNE UN PROCEDE DE DURCISSEMENT DES MOULES ET NOYAUX DE FONDERIE. SELON L'INVENTION, ON DURCIT UNE COUCHE DE SABLE PAR CONGELATION DE SES COMPOSANTS LIQUIDES PAR SUITE DU CONTACT DU SABLE AVEC UN MODELE OU UNE BOITE A NOYAUX REFROIDIS JUSQU'A UNE TEMPERATURE INFERIEURE A CELLE DE SOLIDIFICATION DES COMPOSANTS LIQUIDES DU SABLE. LA METHODE DE DURCISSEMENT DES MOULES ET NOYAUX DE FONDERIE TROUVE SON APPLICATION AUSSI BIEN DANS LA PRODUCTION DES MOULAGES PAR UNITE QUE DANS CELLE EN SERIE.
