Abstract

LANZADERA PARA LA INYECCION POR ARRIBA DE OXIGENO DE AFINO EN LOS BAÑOS DE METALES O DE FERRO-ALEACIONES CONTENIDAS EN RECIPIENTES METALURGICOS. LA LANZADERA CONTIENE EN SU PARTE TERMINAL UNA TOBERA DE LAVAL QUE DELIMITA EN LA DIRECCION DE FLUJO DE GAS PRIMERO UNA ZONA CONVERGENTE, DESPUES UN CUELLO CILINDRICO Y FINALMENTE UNA ZONA DIVERGENTE. COMPRENDE, POR OTRA PARTE, UN CUERPO DE RECTIFICACION CENTRAL, MOVIL, SENSIBLEMENTE CILINDRICO, QUE SE PUEDE AVANZAR O RETROCEDER AXIALMENTE EN LA ZONA DEL CUELLO DE LA TOBERA DE LAVAL. LA PUNTA DEL CUERPO DE RECTIFICACIONB CENTRAL TIENE UN PERFIL ESPECIAL, QUE DELIMITA, JUNTO CON LA PARED CILINDRICA COAXIAL EXTERIOR DE LA TOBERA DE LAVAL, UNA ZONA DIVERGENTE QUE PROVOCA UNA EXPANSION DEL FLUJO GASEOSO. EL PERFIL DE LA PUNTA DEL CUERPO CENTRAL MOVIL Y EL DEL CONVERGENTE DE LA TOBERA DE LAVAL SON POR LO MENOS APROXIMADAMENTE COMPLEMENTARIOS. LAS CARACTERISTICAS DEL FLUJO GASEOSO SE MODIFICAN CAMBIANDO SU PERFIL DE PASO POR DESPLAZAMIENTO AXIAL DE LAPUNTA DEL CUARPO DE RECTIFICACION CENTRAL.
