Title:
TEMPERATURE CONTROL DEVICE FOR ENDLESS ROLLING LINE
Document Type and Number:
WIPO Patent Application WO/2019/026292
Kind Code:
A1
Abstract:
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.
