Abstract
SE DESCRIBE UN PROCEDIMIENTO PARA HACER FUNCIONAR UN HORNO DE FUSION DE CUPULA, EN EL QUE EL MATERIAL DE CARGA METALICO, LOS ELEMENTOS DE ALEACION Y LAS SUBSTANCIAS QUE TRANSPORTAN ENERGIA, COMO EL CARBON DE COQUE SE AÑADEN EN LA PARTE SUPERIOR (1) DE LA CUBA. EN LA PARTE INFERIOR (2) DE LA CUBA SE AÑADE UN MEDIO OXIDANTE, POR EJEMPLO AIRE. SE INTRODUCEN ADITIVOS, TALES COMO ELEMENTOS DE ALEACION, VIRUTAS METALICAS, CARBON, ARENA Y POLVO DE DIFERENTES TIPOS, BIEN SEA INDIVIDUALMENTE EN COMBINACION, DENTRO DE LA SECCION DE FUSION (5), EN AL MENOS UNA PRIMERA COLADA. LOS COMBUSTIBLES PUEDEN TAMBIEN CARGARSE EN LA PRIMERA COLADA, SI SE DESEA JUNTO CON OXIGENO. ESTE PROCEDIMIENTO SE CARACTERIZA PORQUE EL OXIGENO SE INTRODUCE EN LA SECCION DE FUSION A GRAN VELOCIDAD EN AL MENOS UNA SEGUNDA COLADA SEPARADA, Y PORQUE LAS CONDICIONES EN QUE LAS SUBSTANCIAS ARRIBA MENCIONADAS SE CARGAN EN LA PRIMERA COLADA Y EL OXIGENO SE CARGA EN UNA SEGUNDA COLADA, SE CONTROLAN DE MANERA QUE SE IMPIDA LA FORMACIONDE UNA LLAMA. EL PROCEDIMIENTO PERMITE UNA ADAPTACION FLEXIBLE PARA EL CAMBIO DE LAS CONDICIONES DE FUNCIONAMIENTO A LA CALIDAD OPTIMA GARANTIZADA DE LA MASA FUNDIDA, EN UNA OPERACION IGUALMENTE CUMPLIDORA DE LAS NORMAS MEDIOAMBIENTALES.
