Abstract

La solicitud se refiere a un procedimiento para la fabricacion de un fleje (1) de acero, en el cual se cuela primero en una máquina de colada (2) un desbaste plano (3), en donde el desbaste plano (3) sale de la máquina de colada (2) con una velocidad de colada (v) con un espesor de desbaste plano (H) dado, en donde el desbaste plano (3) es laminado a continuacion en por lo menos un tren de laminacion (4,5) con un numero de cajas de laminacion (6, 7) al fleje (1) y en donde el fleje (1) presenta un espesor final (dF) después de la ultima caja de laminacion (6,7). Para mantener condiciones de procesamiento optimas y/o poder reaccionar frente a eventos inesperados, la presente prevé los siguientes pasos del procedimiento: a) definir una relacion funcional en un control de máquina (8) entre la velocidad de colada (v) o el flujo de masa como producto de la velocidad de colada y el espesor del desbaste plano (v x H) o como producto de la velocidad del fleje y el espesor del fleje y la temperatura del fleje (T) detrás de la ultima caja de laminacion (7), que lamina el fleje (1), para un numero variable (n) de cajas de laminacion (7) activas y espesores finales diferentes; b) determinar o prefijar la velocidad de colada (v) o el flujo de masa (v x H) e ingresar el valor determinado en el control de la máquina (8); c) determinar automáticamente el numero optimo de cajas de laminacion (7) activas y de los espesores finales laminables y reducciones de espesores en el tren de laminacion en base a los desarrollos funcionales almacenados segun el paso a) en el control de la máquina (8), para alcanzar con la velocidad de colada (v) dada y/o el flujo de masa dado (v x H), una temperatura de fleje (T) deseada detrás de la ultima caja de laminacion activa (7); d) eventualmente atravesar un numero de cajas de alimentacion (7) del tren de laminacion (5), de modo que solo el numero de cajas de laminacion (7) determinado de acuerdo con el paso c) está activo.
