Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA EL ACCIONAMIENTO DE UN HORNO DE CUPULA PARA LA GENERACION DE HIERRO FUNDIDO. EN EL ACCIONAMIENTO APARECE EN EL HORNO DE CUPULA DE FORMA ESPECIAL EN LA ZONA DE FUSION UNA FORMACION DE CO ACOMPAÑADA DE VENTAJAS. ESTA FORMACION DE CO FLUCTUA CON LA CONDICION DE COQUE DE RELLENO Y ALCANZA EN DETERMINADOS CASOS DE SERVICIO VALORES BAJOS NO DESEADOS. PARA CONTRARRESTAR ESTE EFECTO, SE PROPONE, QUE EN EL HORNO DE CUPULA SE INTRODUZCA UN GAS CARBONICO (CO2 O CO) EN CANTIDAD ADECUADA Y EN EL LUGAR APROPIADO, CON PREFERENCIA EN LA ZONA DE FUSION O DE VIENTO.
