Abstract

PARA LA FABRICACION DE ACERO EN UN HORNO ELECTRICO DE ARCO INDEPENDIENTEMENTE DE LOS PRECIOS DE MATERIA PRIMA, EN PARTICULAR DE LOS PRECIOS DE LA CHATARRA, ASI COMO PARA ACORTAR LOS TIEMPOS DE FUNDIDO EN EL HORNO, SE PROPONE QUE EL HORNO DE ACERO ELECTRICO DE ARCO SE CARGUE COMO MUCHO CON EL 60 % DE CHATARRA (10), ASI COMO MUCHO EL 60 % CON UN HIERRO EN BRUTO (QUE ESTA LIQUIDO) Y QUE SE OBTIENE DE UN ALTO HORNO DE PEQUEÑO TAMAÑO (1), ASI COMO SI SE QUIERE CON OTROS ELEMENTOS DE HIERRO (11, 11.1), DE TAL MANERA QUE EL PROCESO DE FUSION SE REALICE EN EL HORNO DE ACERO DE ARCO (12) UTILIZANDO ENERGIA ELECTRICA, ASI COMO UTILIZACION SIMULTANEA DE OXIGENO Y CARBON DE INYECCION.
