Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA LA FABRICACION DE PRODUCTOS DE ACERO LAMINADO, P.EJ. ACEROS TENSADOS ATORNILLABLES O SIMILARES, EN EL QUE LOS ACEROS CON UN CONTENIDO DE C DE 0,50 A 8,80 % DE SU PESO, UN CONTENIDO DE SI DE 0,20 A 0,60 % DE SU PESO Y UN CONTENIDO DE MN DE 0,30 A 0,80 % DE SU PESO, SON SOMETIDOS DESPUES DEL LAMINADO EN CALIENTE EN LA PARTE DE EVACUACION DEL BASTIDOR DE LAMINADO DE ACABADO, FUERA DE LA ZONA CALIENTE, A UN ENFRIAMIENTO DE LA SUPERFICIE, DE TAL FORMA QUE, EL MATERIAL EN UNA ZONA PERIFERICA, SE TRANSFORMA INMEDIATA Y TOTALMENTE EN MARTENSITA, MIENTRAS QUE EL CALOR CONTENIDO EN LA ZONA DEL NUCLEO DURANTE EL ENFRIAMIENTO POSTERIOR, NO PROVOCA UN REVENIDO EN UNA ZONA PERIFERICA DE MARTENSITA, POR ENCIMA DE LA ZONA DE LA ETAPA INTERMEDIA, Y QUE SE CARACTERIZA SEGUN LA INVENCION, PORQUE DESPUES DEL ENFRIAMIENTO SE PRODUCE UNA DEFORMACION EN FRIO, Y A CONTINUACION UN REVENIDO. EL GRADO DE EXTENSION ALCANZA PREFERENTEMENTE DEL 0,5 AL 1,5 %; EL REVENIDO SE EFECTUA PREFERENTEMENTE A UNA TEMPERATURA EN EL MARGEN DE 350 (GRADOS) C A 380 (GRADOS) C, Y DURANTE UN TIEMPO DE PERMANENCIA A UNA TEMPERATURA MAXIMA DE 5 A 60 SEGUNDOS. CON ESTE PROCEDIMIENTO PUEDEN SER FABRICADOS DE FORMA SENCILLA Y RENTABLE ECONOMICAMENTE PRODUCTOS DE ACERO LAMINADOS, COMO P.EJ. ACEROS TENSADOS, LOS CUALES CORRESPONDEN TOTALMENTE A LAS NECESARIAS EXIGENCIAS EN OBRAS, CON VISTAS A LA DEFORMACION Y PROPIEDADES MECANICAS.
