本文对二十辊轧机的力能参数进行了理论分析。通过对其最外层支承辊径向调节灵敏度的计算，发现每种径向调节形式都存在最佳初始位置，并且最佳位置与所调轧辊的合力作用线方向相垂直，从而为实际生产中确定径向调节偏心的初始位置提供了理论依据 In this paper, the theoretical analysis of the power parameters of twenty-high mill is carried out. Through the calculation of the radial adjustment sensitivity of the outermost support roller, it is found that each radial adjustment form has the best initial position, and the optimal position is perpendicular to the resultant force line of the adjustment roller so as to be practical in production To determine the initial position of radial adjustment eccentricity provides a theoretical basis
