Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA FABRICACION DE PRODUCTOS ESTIRADOS EN CALIENTE, ESPECIALMENTE BARRAS O TUBOS, DE ACERO DE ALTA ALEACION O HIPEREUTECTICO, EN EL CUAL LA LONGITUD UTIL DEL MATERIAL ELEGIDO SE CALIENTA A LA TEMPERATURA DE MOLDEADO, DESPUES DE UNO O MAS PASOS DE MOLDEADO SE VUELVE A CALENTAR A UNA TEMPERATURA POR DEBAJO DE LA TEMPERATURA ORIGINAL DE MOLDEADO, SE LAMINA DE FORMA CONTINUA EN UNA LAMINADORA MULTIETAPA A SU DIMENSION FINAL Y A CONTINUACION SE ENFRIA CON AIRE EN REPOSO. LA INVENCION SE CARACTERIZA POR GENERAR, DESPUES DEL PRIMER PASO DE MOLDEADO Y ANTES DEL SEGUNDO CALENTAMIENTO, UN PRODUCTO INTERMEDIO CON UNA DISTRIBUCION UNIFORME DE TEMPERATURA EN TODA SU LONGITUD Y ESPESOR MEDIANTE CALENTAMIENTO O ENFRIAMIENTO CONTROLADO HASTA UNA TEMPERATURA PREDETERMINADA DENTRO DE UN RANGO DE TEMPERATURA.
