Abstract
SE PRESENTA UN METODO DE FUSION PARA UN HORNO DE ARCO ELECTRICO CON FUENTES ALTERNATIVAS DE ENERGIA PARA LA FUSION DE ALEACIONES BASADAS EN HIERRO. EL HORNO ELECTRICO (10) INCLUYE UNAS TOBERAS (13) POSICIONADAS SOBRE EL FONDO PARA SUMINISTRAR OXIGENO, AL MENOS UNA TOBERA (15) PARA SUMINISTRAR POLVO DE CARBON QUE TRABAJA EN EL AREA DE CONTACTO ENTRE EL BAÑO DE METAL FUNDIDO (16) Y LA CAPA DE ESCORIA (22), AL MENOS UNA LANZA SUPERSONICA (12) QUE COOPERA CON UNA LANZA (29) PARA SUMINISTRAR POLVO DE CARBON, ESTAS LANZAS (12, 29) TIENEN UNA POSICION DE TRABAJO (12C, 29C) EN LA CUAL LA LANZA SUPERSONICA (12) SE POSICIONA MUY CERCA DE LA SUPERFICIE DEL METAL FUNDIDO (16) Y LA LANZA (29) PARA SUMINISTRAR POLVO DE CARBON SE POSICIONA EN LA PROXIMIDAD DE LA SUPERFICIE DE LA CAPA DE ESCORIA (22), Y UNA PLURALIDAD DE QUEMADORES (28) POSICIONADOS SOBRE LAS PAREDES LATERALES ENFRIADAS (31) DEL HORNO (10) Y QUE SUMINISTRAN GASES BASADOS EN OXIGENO Y SUBSTANCIAS COMBUSTIBLES, MEDIANTE LO CUAL AL MENOS LOSDOS PRIMEROS QUEMADORES (28) TRABAJAN CON LA ACCION DE UN QUEMADOR QUE SOPORTA LA ACCION DEL SIGUIENTE, EL HORNO (10) SE CARGA CON UNA O MAS CARGAS QUE SUMINISTRAN UN PRIMER PASO O INICIO DE LA FUSION Y UN SEGUNDO PASO DE FUSION, TAMBIEN PUEDEN INCLUIRSE UN PASO DE REFINAMIENTO Y UN PASO DE COLADA, EN EL METODO EN EL PRIMER PASO DE INICIO DE LA FUSION AL MENOS UN SEGUNDO QUEMADOR (28E) COLABORA EN LA LIBERACION RAPIDA DEL CAMINO DE INTRODUCCION DE LA LANZA SUPERSONICA (12) Y DE LA LANZA (29) PARA SUMINISTRAR POLVO DE CARBON, AL MENOS UN TERCER QUEMADOR (28A) SE DIRIGE HACIA EL CENTRO DEL HORNO (10) EN COOPERACION CON EL AREA DE EMERGENCIA DEL OXIGENO SUMINISTRADO POR UNA TOBERA DE OXIGENO (13) HACIA LA SUPERFICIE DEL BAÑO, LOS QUEMADORES (28) TRABAJAN EN EL PRIMER PASO COMO QUEMADORES Y EN EL SEGUNDO PASO COMO LANZAS DE OXIGENO SUBSONICAS Y EN EL TERCER PASO ESTAN SUBSTANCIALMENTE APAGADOS, LAS TOBERAS DE OXIGENO (13) SUMINISTRAN OXIGENO EN UNA GRAN CANTIDAD Y A BAJA PRESION, EL SUMINISTRODE SUBSTANCIAS CARBONACEAS SE DIRIGE HACIA EL CENTRO DEL HORNO (10) Y ACTUA EN COOPERACION CON LA ESCORIA (22) TANTO ENCIMA DE LA ESCORIA COMO ENTRE LA ESCORIA Y EL METAL FUNDIDO, LAS REACCIONES FE + O = FEO, FEO + C = FE + CO SON PROVOCADAS DENTRO DEL BAÑO DE METAL FUNDIDO (16) JUSTO POR ENCIMA DE LA SUPERFICIE DEL METAL FUNDIDO (16) Y ALREDEDOR DEL GROSOR DE LA ESCORIA (22), QUE SE PROCESA PARA QUE SEA ESCORIA ESPUMOSA, Y LA REACCION CO + O = CO{SUB,2} SE HACE QUE TENGA LUGAR JUSTO ENCIMA DE LA SUPERFICIE DEL METAL FUNDIDO (16) Y ALREDEDOR DEL GROSOR DE LA ESCORIA (22). SE PRESENTA UN HORNO DE ARCO ELECTRICO QUE LLEVA A CABO EL METODO DESCRITO.
