Title:
TEMPERATURE CONTROL UNIT OF HOT-ROLLING MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/118606
Kind Code:
A1
Abstract:
A temperature control unit of a hot-rolling machine according to the present invention extracts a high-frequency component, a mid-frequency component, and a low-frequency component on the basis of a difference between a provided temperature target value and a calculated or measured value of a material temperature in a temperature-managing position set on the output side of the hot-rolling machine. A reference value of electric power in an induction heating device set for a power conversion device is corrected on the basis of the high-frequency component, a reference value of a cooling water flow amount set for a flow amount conversion device is corrected on the basis of the mid frequency component, and a reference value of a roll rotation speed set for a speed conversion device is corrected on the basis of the low frequency component.
