Method of Roll Eccentricity Compensation for Single Stand Reversible Cold Rolling Mill

Based on eccentricity control principle and eccentricity signal model,an eccentricity compensation project for single stand and reversing cold strip mill was studied.The examination and calculation process of this project is simple.Sampling at same distance is adopted to collect data,which avoids the disadvantage of the traditional method.The project has been applied to the gauge control system of 1650 mm reversible cold strip mill in Tanggang.The practical effect is obviously good.The gauge deviation can be controlled in ±5 μm.
