Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO Y UN DISPOSITIVO PARA ENFRIADO DE PERFILES LAMINADOS EN CALIENTE A PARTIR DE PROCESO DE LAMINADO DE RODILLOS, DONDE LOS PERFILES SE CONFIGURAN CON PARTES PERFILADAS (1-5) DISPUESTAS CON UNA DISTANCIA A TRAVES DE LA SECCION TRANSVERSAL DE MASAS DIFERENTES POR EJEMPLO COMO CARRILES, SIENDO MEJORADO DE TAL MODO, QUE PRIMERO SE APLICA BAJO UTILIZACION DE MEDIOS (30-32) DE TECNICA DE MEDICION EN ACCION CONJUNTA CON UNA UNIDAD (40) DE CALCULO CON AYUDA DE UN PROGRAMA DE ORDENADOR, QUE SE REFIERE A LAS PARTES (1-5) DE PERFILES DIFERENTES SEGUN LA INFORMACION DE MASA Y TEMPERATURA CON RESPECTO A LA CANTIDAD DE CALENTAMIENTO A SER APLICADA Y SE DETERMINAN LOS MEDIOS (48) DE ENFRIAMIENTO DE ACUERDO CON LA CANTIDAD DE CESION NECESARIA. SE CALCULA DESPUES DEL ENFRIAMIENTO DE LAS PARTES (1-5) PERFILADAS DIFERENTE O DE SUS MASAS QUE SE REALIZAN DE FORMA CONTROLADA DE TAL MODO, QUE SE CONSIGUE UNA UTILIZACION DE TIEMPO LO MAS REDUCIDA POSIBLE DE LAS LINEAS DE TRANSFORMACION A{SUB,R3}/A{SUB,R1} EN CASO DE DESMENUZAMIENTO DE LOS CRISTALES DE MEZCLA-GAMMA EN FERRITA Y/O PERLITA BAJO LIBERACION DEL CALOR DE TRANSFORMACION.
