Abstract

Un método para el control de la forma en un laminador de acuerdo con la presente invención incluye: una etapa de medición de medir la forma de una lámina de acero en un lado de entrega del laminador; y una etapa de control para controlar el laminador de manera que la forma de la lámina de acero se encuentre dentro de un intervalo permitido, con base en la forma de la lámina de acero medida en la etapa de medición, en donde la etapa de control incluye una etapa de establecer una ganancia de control más pequeña que una ganancia de control para un ancho de una lámina de acero como objetivo para laminar que es igual o más pequeña que el valor predeterminado cuando la lámina de acero como objetivo para laminar tiene un ancho mayor que un valor predeterminado.
