Abstract

DONDE EL METODO COMPRENDE CALENTAR UNA MATERIA PRIMA FORMADA POR UN REDUCTOR CARBONOSO Y UNA SUSTANCIA QUE CONTIENE OXIDO DE HIERRO EN UN HORNO DE FUSION DE REDUCCION PARA SOMETER EL OXIDO DE HIERRO A REDUCCION DE ESTADO SOLIDO; Y, CARBURIZAR EL HIERRO REDUCIDO CON CARBONO CONTENIDO EN EL REDUCTOR CARBONOSO, PARA QUE EL HIERRO REDUCIDO SE FUNDA A LA VEZ QUE SE SEPARAN LOS COMPONENTES DE GANGA Y COALESCA AL HIERRO METALICO GRANULAR, FORMANDOSE UNA CAPA DE DEPOSITO QUE CONTIENE ESCORIA PRODUCIDA EN EL PROCESO DE FUSION DE REDUCCION SOBRE LOS REFRACTARIOS DE SOLERA, PROTEGIENDOLOS A LA VEZ QUE SE PRODUCE EL HIERRO METALICO. ADEMAS MEDIANTE UN DISPOSITIVO DE ALIMENTACION SE CARGA UN AGENTE DE AJUSTE DE ATMOSFERA DE UN MATERIAL CARBONOSO A TRAVES DE UN CONDUCTO DE SUMINISTRO QUE SE CONECTA VERTICALMENTE CON UNA PORCION DEL HORNO DEL TIPO DE SOLERA MOVIL, ANTES DE QUE SE FUNDA LA MATERIA PRIMA
