Title:
TEMPERATURE CONTROL DEVICE FOR HOT ROLLING LINE
Document Type and Number:
WIPO Patent Application WO/2020/261444
Kind Code:
A1
Abstract:
Provided is a temperature control device for a hot rolling line having a ROT cooling device and an accelerated cooling device, the temperature control device enabling an increase in the accuracy of a temperature model of a rolled material. The temperature control device for a hot rolling line is provided with: a ROT side calculation unit which, in a temperature model for predicting the temperature of a rolled material with respect to a ROT cooling device that injects water to the rolled material, calculates a predicted value of the temperature of the rolled material using a ROT side water-cooled heat transfer coefficient representing the amount of heat removed per unit area during cooling by water; and an acceleration side calculation unit that is provided on an upstream side or a downstream side of the ROT cooling device, and which, in a temperature model for predicting the temperature of the rolled material with respect to an accelerated cooling device that injects water to the rolled material under a different condition from the ROT cooling device, calculates a predicted value of the temperature of the rolled material using a value which is set, separately from the ROT side water cooling heat transfer coefficient set by the ROT side calculation unit, as an acceleration side water cooling heat transfer coefficient representing the amount of heat removed per unit area during cooling by water.
