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.THE INVENTION RELATES TO A PROCESS FOR CURING FOUNDRY MOLDS AND CORES. ACCORDING TO THE INVENTION, A SAND LAYER IS HARDENED BY FREEZING ITS LIQUID COMPONENTS AS A RESULT OF CONTACT OF THE SAND WITH A COOLED MODEL OR CORE BOX TO A TEMPERATURE LOWER THAN THAT OF SOLIDIFICATION OF THE LIQUID COMPONENTS OF SAND. THE METHOD OF HARDENING MOLDS AND FOUNDRY CORES FINDS ITS APPLICATION AS WELL IN THE PRODUCTION OF CASTINGS PER UNIT AS IN THAT IN SERIES.
