Coupling vibration model for hot rolling mills and its ...
The vibration frequency for the hot rolling mill in general is 10-70 Hz. As a result, the vibration increases with mill modulus control AGC gain for the large sensitivity frequency range of hot rolling mills. For these frequencies, the mill modulus control gain can be decreased to relieve mill vibration. 5.
