Abstract
método de laminação de produto de metal laminado plano. a presente invenção tem como seu objetivo ser capaz de proporcionar uma função de controle de coroa/formato de alta resposta a um laminador com uma resposta de dispositivos de felxão de diminuição inferior aos dispositivos de flexão de aumento mesmo sob condições que fazem com que a força de flexão de diminuição de laminador atue. para alcançar esta tarefa, antes do início de laminação, não só a força de flexão de aumento mas também a força de flexão de diminuição são feitas para atuarem e a força composta cosntituída por uma força de flexão do laminador que corresponde à força de equilíbrio do laminador é feita para atuar em um calço do laminador de trabalho. no momento do início de laminação, a força de flexão de diminuição é mantida em um valor constante enquento a força de flexão de aumento é feita para mudar e uma força composta constituída por uma predeterminada força de flexão do laminador (força de flexão de diminuição) é feita para atuar no calço do laminador de trabalho para laminação. no momento do final de laminação, a força de flexão de aumento é retornada para o estado antes do início de laminação e uma força composta com a força de flexão constituída pela força de flexão do laminador correspondente à força de equilíbrio do laminador é feita para atuar no calço do laminador de trabalho. naquele estado, a laminação é terminada.lamination method of flat rolled metal product. The present invention aims to be able to provide a high response crown / shape control function to a rolling mill with a lower shrink fit response to the increase bending devices even under conditions that cause the force rolling mill decrease bending force. To achieve this task, before rolling, not only the bending force but also the bending force are made to act and the composite force consists of a bending force of the rolling mill that corresponds to the balancing force of the Laminator is made to act on a working laminator shim. at the time of rolling, the decreasing bending force is kept constant while the rising bending force is made to change and a composite force consisting of a predetermined rolling bending force (decreasing bending force) It is made to work on the shim of the rolling mill. At the time of the end of rolling, the increasing bending force is returned to the state before the rolling begins and a composite force with the bending force constituted by the bending force of the rolling mill corresponding to the balancing force of the rolling mill is made to act. on the working laminator shim. In that state, the lamination is completed.
