Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y UN DISPOSITIVO PARA TRATAMIENTO TERMICO DE MATERIAL LAMINADO PERFILADO, EN PARTICULAR DE RAILES. PARA LA MEJORA DE LAS PROPIEDADES DE UTILIZACION DE HA PREVISTO QUE EL MATERIAL DE LAMINADO CON UNA TEMPERATURA COMO MAS ALTA DE 1.100 ALCANCE SU CONFORMACION PLASTICA Y EN UNA PRIMERA ETAPA DE ENFRIAMIENTO SE ENFRIE CON UNA INTENSIDAD DE REFRIGERACION DE IGUALDAD LOCALIZADA SOBRE UNA TEMPERATURA, EN PARTICULAR DE 5 HASTA 120 EN UNA SEGUNDA ETAPA EL MATERIAL DE LAMINACION EN DIRECCION LONGITUDINAL SE SOMETA A EXTRACCION TERMICA DE INTENSIDAD DIFERENTE PERIMETRICA CON IGUALDAD LOCALIZADA, VISTA EN SECCION TRANSVERSAL Y CON INTENSIDAD DE ENFRIAMIENTO ELEVADA POR ZONAS QUE SON COORDINADAS CON ALTA CONCENTRACION DE MASA, EN DONDE LAS ZONAS SE CONFIGURAN EN ESTRUCTURA PERLITICA FINA LIBRES DE MARTENSITA, CONSIGUIENDOSE SOBRE UN ENFRIAMIENTO ALCANZAR LA TEMPERATURA AMBIENTE. UN EQUIPO DE ACUERDO CON LA INVENCION SE CARACTERIZA POR UNA ZONA (A) DE AJUSTE PREVIO, UNA ZONA (B) DE TRATAMIENTO DE ENFRIAMIENTO Y UNA ZONA (C) DE ENFRIAMIENTO TERMINAL PARA EL MATERIAL LAMINADO PERFILADO.
