Abstract

LA INVENCION ESTA RELACIONADA CON UN METODO DE FABRICACION DE HIERRO FUNDIDO GRAFITICO COMPACTADO. SE AÑADEN AGENTES DE ALEACION QUE MODIFICAN EL GRAFITO, UNA CONOCIDA ALEACION DE TRATAMIENTO (6), AL HIERRO FUNDIDO LIQUIDO (9). LA ALEACION DE TRATAMIENTO SE AÑADE AL HIERRO LIQUIDO PULVERIZANDOLA EN EL CHORRO (10) DEL HIERRO LIQUIDO A MEDIDA QUE ESTE ULTIMO SE DESCARGA DESDE EL HORNO DE FUNDICION. SE MANTIENE UNA CANTIDAD CERRADA DEL HIERRO TRATADO DURANTE UN PERIODO DE TIEMPO PREDETERMINADO EN EL INTERIOR DE UNA CAJA DE MOLDEO (3) PARA LA HOMOGENEIZACION Y LA FLOTACION DE LA ESCORIA, DESPUES DE LO CUAL SE VIERTE EN UN MOLDE (1).
