Abstract
Un proceso para producir hierro metalico y escoria mediante la fundicion de una materia prima con contenido de hierro, que posee hierro presente como oxido o en un estado parcialmente metalizado, en un reactor que contiene un bano liquido que comprende o que posee una fase de escoria, utiliza la inyeccion de combustible, agente reductor y gas oxigenado en la escoria, mediante cuando menos una lanza de manguera sumergida en la parte superior, para generar condiciones de calentamiento y reduccion en cuando menos una region reductora en el bano. Se alimenta la materia prima al reactor, junto con un agente reductor adicional y flujo, en, o adyacente a, cuando menos una region reductora, con lo que se somete la material prima a reduccion de fundicion, que genera gases combustion que comprenden CO y H2. Se controlan las velocidades de inyeccion del gas oxigenado, combustible y agente reductor mediante la cuando menos una lanza de manguera para obtener las suficientes condiciones reductoras requeridas; y, en el reactor por encima del bano, se produce post-combustion de los gases de combustion generados por la fundicion. El control del paso (c) hace que el gas oxigenado tenga un contenido de oxigeno de 40% a aproximadamente 100% del volumen, y sea suficiente para un grado de combustion de mas del 60% del peso del combustible y agente reductor inyectados mediante la cuando menos una lanza de manguera.
