Abstract

PROCEDIMIENTO PARA LA FABRICACION DE ACEROS CON BAJO CONTENIDO DE CARBONO, BAJO VACIO, MEDIANTE LA INSUFLACION DE OXIGENO, LA REGULACION DEL PUNTO FINAL DE CARBONO Y LA REGULACION DE LA TEMPERATURA DE INSUFLACION.CONSISTE EN QUE MIENTRAS SE EFECTUA LA ALIMENTACION DE OXIGENO DESDE ARRIBA MEDIANTE LA LANZA DE INSUFLACION Y SE BARRE LA MASA FUNDIDA DESDE ABAJO MEDIANTE ARGON, SE MIDE DE MANERA CONTINUA LA COMPOSICION, LA TEMPERATURA Y LA CANTIDAD DE AGUA DE REFRIGERACION ALIMENTADA Y EVACUADA, REGULANDOSE EN FUNCION DE ELLAS LA INTENSIDAD DEL ARGON. LAS ETAPAS TECNOLOGICAS SE REALIZAN TODAS ELLAS EN BASE A LOS RESULTADOS DE MEDICION OBTENIDOS.
