Abstract

UN MATERIAL CARBONACEO SE CONTROLA DE MANERA QUE LA CANTIDAD DE CARBON SEA DEL 7 AL 60% EN MASA, BASADO EN LA CANTIDAD TOTAL DE HIERRO Y ZN, EN UNA MEZCLA INICIAL FORMADA POR UNO O MAS CONDUCTOS QUE CONTIENEN OXIDO DE HIERRO Y OXIDO DE ZN, Y UN AGLUTINANTE EN CANTIDAD SUFICIENTE PARA AGLUTINAR LOS POLVOS, AÑADIENDOSE AGUA PARA PREPARAR GRANULOS VERDES QUE LLEVAN INCORPORADO EL MATERIAL CARBONACEO. A CONTINUACION, SE PREPARAN GRANULOS SECOS, POR SECADO DE LOS GRANULOS VERDES ASI PREPARADOS EN UN HORNO REDUCTOR, LOS GRANULOS SECOS SE CALIENTAN POR TRANSFERENCIA TERMICA, PRINCIPALMENTE POR RADIACION, DE MANERA QUE LA VELOCIDAD DE SUBIDA DE LA TEMPERATURA SEA DE 3 A 13°C/SEG DENTRO DE UNA ESCALA DE TEMPERATURAS DE 150 A 900°C DE LOS GRANULOS, REDUCIENDOSE DE ESE MODO EL OXIDO DE ZN Y EVAPORANDOSE EL ZN, AL TIEMPO QUE SE REDUCE EL OXIDO DE HIERRO PARA PRODUCIR GRANULOS DE HIERRO REDUCIDOS.
