Abstract

Procedimiento para el endurecimiento de elementos de fundición hechos de arena-resina, tales como moldes,npyos y otros, caracterizado por el hecho de que consiste en formar una mezcla gaseosa e inexplosiva de dimetiletilamina y gas carbónico, haciendo borbotear el as en la dimetiletilamina líquida y haciendo pasar la mezcla gaseosa durante un tiempo muy corto a través del elemento de fundición a endurecer.
