Research on Wrapping Angle Compensation Technology of Cold Strip and its Industrial Application

In the paper, the cold strip online dynamic wrapping angle compensation model is established based on the latest intelligent shape meter developed by Yanshan university. It could improving recisions of the shape detection and the shape closed-loop control under specific working conditions effectively. The model was successfully applied to Angang HC 6-high reversible cold rolling mill, meeting bad working conditions on site. The remarkable results were obtained in industrial application. The error between calculated values and measured values of total tensions is within 3%.
