Abstract

PARA EL CONFORMADO DE BRIQUETAS CALIENTES, EL HIERRO ESPONJOSO GRANULADO ES CARGADO EN UNA PRENSA DE CILINDROS A UNAS TEMPERATURAS DE 600 A 850 (GRADOS) C. PARA ELLO SE HACE UNA ESTRUCTURA DE CINTA DE HIERRO ESPONJOSO CON UNAS BRIQUETAS CALIENTES CONFORMADAS Y DISPUESTAS A DISTANCIA UNAS DE OTRAS. MEDIANTE EL GOLPEO DE LA ESTRUCTURA DE CINTA SE SEPARAN LAS BRIQUETAS CALIENTES, PRODUCIENDOSE LA FRAGMENTACION DE LA ESTRUCTURA DE CINTA. LAS BRIQUETAS CALIENTES Y AL MENOS UNA PARTE DE LOS FRAGMENTOS SON ENFRIADOS A UNAS TEMPERATURAS DE ENTRE 20 A 400 (GRADOS) C, DESPUES DE LO CUAL LOS FRAGMENTOS Y BRIQUETAS ENFRIADOS SON CONDUCIDOS A TRAVES DE UN TAMBOR GIRATORIO. A PARTIR DE LAS BRIQUETAS Y LOS FRAGMENTOS SE FORMA EN EL TAMBOR GIRATORIO POLVO DE ABRASION DE GRANO FINO. ESTE POLVO DE ABRASION ES POSTERIORMENTE SEPARADO DE LAS BRIQUETAS Y FRAGMENTOS YA QUE SE COMPORTA DE FORMA PIROFORA.
