Abstract

La invención se refiere a un método para controlar un tren de laminación reductor de estiramiento, en donde se optimizan los externos de los tubos estirados mediante el control de uno o más motores del tren de laminación reductor de estiramiento (1), que comprende al menos una medición del espesor de la pared del lado de salida y un ajuste automático de la magnitud del cambio de velocidad de los motores al perfil de espesor de la pared del tubo, en donde el curso temporal de los cambios de velocidad de los motores individuales o de todos los motores también se ajusta de manera automática en función de las mediciones del espesor de la pared del tubo.
