Title (EN) TEMPERATURE CONTROL DEVICE FOR ENDLESS ROLLING LINE
(FR) DISPOSITIF DE RÉGULATION DE TEMPÉRATURE POUR LIGNE DE LAMINAGE SANS FIN
(JA) エンドレス圧延ラインの温度制御装置
Abstract:
(EN) In an endless rolling line, the speed of a rolled material is changed accompanying a flying sheet thickness change. This temperature control device predicts and calculates a speed change amount of the rolled material accompanying a flying sheet thickness change, and updates a speed pattern. The temperature control device performs a feed forward control for a cooling water amount for cooling the rolled material on the basis of the most recent speed pattern and a temperature measurement value of the rolled material at the entrance side of a heat exchanger. The temperature control device performs, concurrently with the feed forward control, a feedback control of the cooling water amount based on the tolerance between a target value and the temperature measurement value of the rolled material at the outlet side of the heat exchanger.
(FR) Selon l'invention, dans une ligne de laminage sans fin, la vitesse d'un matériau laminé est modifiée au fur et à mesure d'un changement d'épaisseur d'une feuille volante. Le dispositif de régulation de température selon l'invention prédit et calcule une quantité de changement de vitesse du matériau laminé accompagnant un changement d'épaisseur de feuille volante et met à jour un motif de vitesse. Le dispositif de régulation de température effectue une commande prédictive pour une quantité d'eau de refroidissement pour refroidir le matériau laminé sur la base du motif de vitesse le plus récent et d'une valeur de mesure de température du matériau laminé au niveau du côté d'entrée d'un échangeur de chaleur. Le dispositif de régulation de température effectue, simultanément avec la commande prédictive, une commande de rétroaction de la quantité d'eau de refroidissement sur la base de la tolérance entre une valeur cible et la valeur de mesure de température du matériau laminé au niveau du côté de sortie de l'échangeur de chaleur.
(JA) エンドレス圧延ラインでは、走間板厚変更に伴い被圧延材の速度が変化する。温度制御装置は、走間板厚変更に伴う被圧延材の速度変化量を予測計算し、速度パターンを更新する。温度制御装置は、最新の速度パターンと、熱交換器の入側における被圧延材の温度計測値と、に基づいて、被圧延材を冷却する冷却水量のフィードフォワード制御を実行する。温度制御装置は、フィードフォワード制御と並行して、熱交換器の出側における被圧延材の温度計測値と、目標値との誤差に基づいた冷却水量のフィードバック制御を実行する。
