Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE METAL EN FUSION EN UN HORNO DE CUBILOTE. UNA VEZ QUE SE HA CARGADO EL HORNO CON METAL Y CON COQUE, SE QUEMA ESTE INTRODUCIENDO DOS GASES CON CONTENIDO DE OXIGENO. UNO DE LOS DOS GASES, QUE TIENE UNA CONCENTRACION DE OXIGENO SUPERIOR A LA DEL OTRO Y COMPRENDIDA ENTRE EL 50 Y EL 100%, SE INTRODUCE EN EL CUBILOTE A UNA VELOCIDAD SUPERSONICA COMPRENDIDA ENTRE 360 Y 914 METROS POR SEGUNDO.
