Abstract

"PROCESSO E APARELHO DE CONTROLE ESTáVEL DE LAMINADOR". Em um controle de estabilização de laminação, um controle diferencial proporcional é realizado em um movimento sinuoso de um material a ser laminado, que é provocado durante um processo de laminação, com base em um desvio lateral das cargas que são detectadas pelos sensores de carga dispostos em um laminador, um valor de instrução de um desvio lateral de nivelamento, que vai ser propiciado a um dispositivo de desbaste, é calculado, e um cilindro de afastamento, com base no valor de instrução para estabilizar o movimento sinuoso do material a ser laminado. Um filtro de estabilização de passo baixo, tendo uma constante de tempo limite, que é substancialmente igual a uma constante de tempo do ponto zero das características de freq³ência operacional do laminador, é disposto.
