Simulation and Analysis of Roller Eccentricity Compensation in Cold Mill

Abstract:

With the increase request of strip quality, the roller eccentricity has become the important factor of influencing product quality. On the practical model of Cold-rolling Mill of 300, this paper establishes eccentricity compensation control practice of Cold-rolling Mill of 300 which applies wavelet transform method. Based on mufti-resolution decomposition of roll force signal by use of wavelets, eccentricity signals are separated from disturbances and noise，and self-optimization is employed to real-time control the roller eccentricity. The results show that the method is effective.
