- Abstract
This article carries out a new method to find out and compensate the roll eccentricity online in the strip cold rolling process. Firstly, the roll eccentricity signals are found out from the massive process data by a soft measurement method, secondly, this signals in time domain is converted into signal in angle domain with strict periodicity. Then the values of roll eccentricity in every sampled angle of one cycle are saved in a special array, and added inverse to the setting value of the position loop of the AGC system, adjusting the roll gap & compensate the roll eccentricity activity. Finally, the rolling experiments prove that this method is accurate and sTable, and the roll eccentricity disturbance is inhibited obviously.
