Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO CARACTERIZADO MEDIANTE COSTES REDUCIDOS DE FUSION Y UN IMPACTO DISMINUIDO AMBIENTAL, ASI COMO UN DISPOSITIVO FACIL DE OPERACION PARA EL FUNDIDO DE MATERIALES METALURGICOS QUE CONTIENEN HIERRO, EN PARTICULAR CHATARRA DE ACERO, EN UN HORNO DE CUPULA CALENTADO CON COKE PARA LA PRODUCCION DE HIERRO FUNDIDO. DE ACUERDO CON EL PROCEDIMIENTO, EL GAS ES GUIADO PARCIALMENTE A TRAVES DEL HORNO A TEMPERATURA POR ENCIMA DE 400 NTO Y SUMINISTRADO DE NUEVO A LAS ZONAS DE FUSION Y DE SOBRECALENTAMIENTO AL MISMO TIEMPO CON MAS DEL 23 DE OXIGENO. OTRO RASGO CARACTERISTICO DE LA INVENCION ES QUE LA CANTIDAD PARCIAL DEL GAS GUIADO A PARTIR DEL HORNO ES IGUAL AL 70 DE LOS GASES DEL HORNO PRODUCIDOS DURANTE EL PROCESO DE FUSION. EL GAS DE HORNO SUMINISTRADO, DEBIDO EN PARTICULAR A SU CONTENIDO EN CO, ASEGURA UN SUMINISTRO DE COMBUSTIBLE GASEOSO QUE ES QUEMADO CON EL OXIGENO. LAS CONDICIONES DE REDUCCION EN LAS CUPULAS CALENTADAS A GAS SE REFUERZAN DE ESTA FORMA, MEJORANDO DE MANERA CORRESPONDIENTE LOS EFECTOS METALURGICOS.
