Research on Stability of High-strength Thin Strip Production Control System
In order to solve the problems including improper AGC adjustment,unstable threading,and strip front/back end whipping during the production process of high-strength thin strip of 1780mm tandem hot rolling mill,this paper optimizes the AGC adjustment limit by tracking the control system,and develops the functions including automatic memory of strip head horizontal value during finishing rolling,automatic leveling of tail end during strip front end whipping and automatic lifting of F7 roll gap after strip back end whipping to realize stable rolling of high-strength thin strip.
