Abstract

EN UN PROCEDIMIENTO DE LAMINADO EN FRIO DE UNA BANDA METALICA (B) ENTRE LOS CILINDROS DE BASTIDOR DE LAMINADOR (C1, C2, C3) DISPUESTOS UNO TRAS OTRO DE OTRO, SE APORTA EN TIEMPO REAL UNA MODIFICACION A LA REFERENCIA DE APRIETE DE LOS CILINDROS DE AL MENOS UNA (C2, C3) DE DICHOS BASTIDORES (C1, C2, C3) PARA COMPENSAR LOS DEFECTOS DE EXCENTRICIDADES DE LOS CILINDROS DE DICHO BASTIDOR (C2, C3), SE EVALUA DICHA MODIFICACION ANALIZANDO EN FRECUENCIA UNA SEÑAL DE MEDICION DE TRACCION DE LA BANDA (B) INMEDIATAMENTE CORRIENTE ARRIBA DE DICHO BASTIDOR (C2, C3) Y EXTRAYENDO DE LA SEÑAL DE MEDICION DE TRACCION, LAS VARIACIONES PERIODICAS DE LA SEÑAL CUYA FRECUENCIAS CORRESPONDEN A LAS VELOCIDADES DE ROTACION DE DICHOS CILINDROS, DE MANERA QUE OBTENGA UNA SEÑAL DE COMPENSACION PROPORCIONAL A LAS VARIACIONES PERIODICAS. SE MEJORA SENSIBLEMENTE EL TIEMPO DE RESPUESTA DE LA REGULACION DE COMPENSACION Y LA HOMOGENEIDAD EN ESPESOR DE LA BANDA (B) EN SALIDA DE LAMINADO. EL DISPOSITIVO DE COMPENSACION (P''2, P''3) ESTA CONECTADO A LOS MEDIOS DE APRIETE (A2, A3) DEL BASTIDOR (C2, C3) Y A UN DETECTOR DE TRACCION (T2, T3) SITUADO INMEDIATAMENTE CORRIENTE ARRIBA DEL BASTIDOR (C2, C3).
