Abstract

Método para la producción de productos planos de metal, en particular bobinas de tiras, en modo sin fin y/o semi-sin fin, en el cual un producto de metal se alimenta de forma continua a un tren de laminación que consta de al menos 4 soportes, en los que los soportes de laminación son, en secuencia, soportes de desbaste (18a, 18b, 18c) y soportes de acabado (21a, 21b, 21c, 21d, 21e), en los que se proporciona para realizar un cambio de espesor al vuelo, específicamente un cambio del grosor sin interrumpir el proceso de laminación, del producto de metal que sale del tren de laminación. Al menos la velocidad de rotación de los rodillos del primer soporte (18a) del tren de laminación y su espacio no se modifican durante el cambio de espesor al vuelo de la tira. La transición del grosor actual al grosor posterior se produce mediante la aplicación de una nueva configuración de parámetros, por ejemplo, el espacio entre los rodillos, la velocidad de los rodillos y la tensión entre los soportes, a todos los soportes de laminación involucrados en el cambio de espesor al vuelo. El número de soportes involucrados en el cambio de espesor al vuelo, comenzando desde el último soporte (21e) de los soportes de acabado, se obtiene teniendo en cuenta la distribución de la fuerza de laminación de cada soporte, de modo que la nueva distribución de fuerzas debido al cambio del grosor no hace que el valor de la fuerza de laminación de ningún soporte salga de un intervalo de tolerancia aceptable.
