Abstract

PROCEDIMIENTO DE REDUCCION DIRECTA EN HORNO ROTATORIO DE MENAS QUE CONTIENEN OXIDOS DE HIERRO. CONSISTE EN LA UTILIZACION DE UN HORNO ROTATORIO Y EN EL USO DE UN AGENTE REDUCTOR CARBONOSO SOLIDO, EMPLEANDO COMO COMBUSTIBLE Y REDUCTOR, Y DE UN AGENTE DE CONTROL DE AZUFRE, TAL COMO PIEDRA CALIZA O DOLOMITA, DE FORMA DE OBTENER UN HIERRO DIRECTAMENTE REDUCIDO CON UN CONTENIDO DE AZUFRE INGERIOR AL 0,02 POR 100 EN PESO. EL CARBON SE ALIMENTA POR EL EXTREMO DE CARGA Y TAMBIEN POR EL EXTREMO DE DESCARGA, INSUFLANDOLO DESDE UN DISPOSITIVO DE FOGONERO CON AIRE A TRAVES DE UN TUBO.
