Abstract

a presente invenção refere-se a um trem de laminação a frio que compreende múltiplos cilindros de ajuste, através do qual uma tira laminada a frio (1) sucessivamente executada. uma velocidade atual (v) na qual a tira laminada a frio (1) é descarregada a partir de um (2-1) dos cilindros de ajuste (2) é medida. a medida da velocidade atual (v) é comparada a uma velocidade desejada correspondente (v*). um valor desejado (vu*) para uma velocidade do cilindro circunferencial (vu) do respectivo cilindro de ajuste (2-1) é ajustado sobre a base da comparação tal que a velocidade atual (v) corresponde á velocidade desejada (v*). o respectivo cilindro de ajuste (2-1) é controlado de acordo com o valor desejado (vu*) ajustado para a velocidade do cilindro circunferencial (vu) do respectivo cilindro de ajuste (2-1). contudo, uma espessura (d) na qual a tira laminada a frio (1) é descarregada a partir do respectivo cilindro de ajuste (2-1) é detectada. um estreitamento (s) do respectivo cilindro de ajuste (2-1) é ajustado sobre a base de pelo menos a espessura detectada (d) da tira na de tal maneira que o produto da velocidade atual (v) da tira laminada a frio (1) e da espessura (d) e da tira (d) corresponde a uma taxa do fluxo de massa desejada (m*).
