摘 要: | 随着对带钢质量要求的提高,轧辊偏心已成为影响产品质量的重要因素.本文在冷轧轧机的板厚控制模型的基础上,建立了300冷轧机的偏心补偿控制方法.本文利用小波对轧制力信号进行多层分解,将偏心信号与干扰和噪声分离,并进行优化补偿,通过实时控制对轧辊偏心进行补偿,仿真结果表明,该方法能够有效补偿轧辊偏心对板厚的影响.

Simulation Study on Roll Eccentricity Compensation in Strip Mill |
| |
Abstract: | With theincrease 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 noiseand self-optimization is employed to real-time control the roller eccentricity.The results show that the method is effective. |
