Title:
SYSTEM AND METHOD FOR CONTROLLING TEMPERATURE PATTERN OF STEEL PLATE IN CONTINUOUS ANNEALING LINE
Document Type and Number:
WIPO Patent Application WO/2018/117297
Kind Code:
A1
Abstract:
The present invention relates to a system for controlling the temperature of a steel plate in a continuous annealing furnace. This system for controlling the temperature of a steel plate comprises: a steel plate temperature input unit (14) into which a target temperature value of a steel plate (7) is input; a behavior-predicting model unit (10) which predicts and calculates in real time a target furnace temperature that matches the input target temperature value of the steel plate; a high-bandwidth inner loop control module (18) which receives the predicted value of the furnace temperature and controls the internal temperature of an annealing furnace (16) to perform a primary adjustment of the temperature of the steel plate (7); and a low-bandwidth outer loop control module (20) which performs a secondary adjustment of the temperature of the steel plate (7) by controlling the steady-state error that is generated relative to the target temperature of the steel plate.
