Abstract

dispositivo de controle de espessura de placa e método de controle de espessura de placa. um dispositivo de controle de espessura de placa é um dispositivo de controle de espessura de placa para controlar a espessura de placa de um laminador a quente fornecido com um suporte de enrolamento. o dispositivo de controle de espessura de placa inclui: um pirômetro disposto no lado de entrada do suporte de enrolamento; uma parte de cálculo de diferença que envia uma diferença de temperatura entre uma temperatura de travamento da placa a ser enrolada, medida pelo pirômetro, e um valor de medição de uma parte além da parte de ponta da placa a ser enrolada, medida pelo pirômetro; uma parte de rastreamento que transfere a diferença de temperatura da posição do pirômetro para imediatamente abaixo do suporte de enrolamento com base na velocidade de placa da placa a ser enrolada; e uma parte de computação que calcula uma quantidade de enroscamento do suporte de enrolamento com base na diferença de temperatura transmitida a partir da parte de rastreamento. a parte de computação pode incluir uma parte de controle proporcional diferencial que realiza o controle proporcional diferencial na diferença de temperatura, e uma parte de cálculo de quantidade de enroscamento que calcula uma quantidade de enroscamento com base em um valor de saída da parte de controle proporcional-diferencial.
