Document Type and Number:
WIPO Patent Application WO/2022/157826
Kind Code:
A1
Abstract:
Provided is a control device for a hot rolling line, whereby destabilization of cooling in the transition boiling region can be suppressed while maintaining responsiveness of feedback control of winding temperature. The control device controls cooling of rolled stock by an upstream-side bank after a reference value for the target temperature of the rolled stock in feed-forward control of the upstream-side bank has been corrected in accordance with a correction value. The control device controls cooling of the rolled stock by feedback control of a downstream-side bank after a reference value for an amount of cooling water supplied to the rolled stock in feedback control of the downstream-side bank has been corrected in accordance with a correction value calculated by a feedback correction value calculation unit.
