Abstract

PROCEDIMIENTO DE ELABORACION DE UN ACERO DE HERRAMIENTAS DESTINADO ESPECIALMENTE A LA FABRICACION DE MOLDES, Y ACERO OBTENIDO POR ESTE PROCEDIMIENTO. --SE ELABORA UN ACERO QUE CONTIENE EN SU COMPOSICION: DEL 0,2 AL 2% DE CARBONO, DEL 0,2 AL 2% DE MANGANESO, DEL 0,35 AL 20% DE CROMO, MENOS DEL 5% DE NIQUEL, MENOS DEL 5% DE MOLIBDENO, MENOS DEL 5% DE VANADIO Y/O CON ADICION DE TUNGSTENO, DEL 0,01 AL 0,02% DE AZUFRE, SIENDO EL RESTO DE HIERRO; --DURANTE SU ELABORACION AL VACIO, SE DESOXIDA EL ACERO EN ESTADO LIQUIDO, AGITANDOLO EN PRESENCIA DE UN ELEMENTO DESOXIDANTE; --SE RESULFURA, EN ATMOSFERA CONTROLADA, EL ACERO EN ESTADO FUNDIDO PARA ALCANZAR UN CONTENIDO DETERMINADO DE AZUFRE; --SE REALIZA UNA COLADA DEL ACERO ASEGURANDO UNA SOLIDIFICACION PROGRESIVA Y REGULAR PARA ELIMINAR LOS RETRASOS LOCALES DE SOLIDIFICACION. EL INTERVALO DEL CONTENIDO EN AZUFRE SE DETERMINA PARA CONCILIAR LAS APTITUDES PARA LA MECANIZACION, Y PARA EL PULIDO Y EL GRANEADO.
