本文通过理论分析和实验研究得出: (1) 异径辊轧制由于一个工作辊直径减小了2/3,从而使轧制压力减小35～55％,大大提高了轧制效率。 (2) 探明了各种因素对侧向力的影响规律。小辊偏移角越大、轧制压下量越大及轧制速度越高,则侧向力越大;反向轧制比正向轧制时侧向力大得多。为了降低侧向力的峰值,使之趋于均化,应该适当减少上传动辊的直径或速度。 (3) 由理论分析推导出一个计算小辊侧向力(F)的简化公式;从保证轧制稳定条件出发,还求出确定小辊合理偏移量(e)的简单公式,通过实验在一定偏移量范围内得到验证。
In this paper, theoretical analysis and experimental study show that: (1) Reducing Roll Rolling As the diameter of a work roll is reduced by 2/3, the rolling pressure is reduced by 35-55%, greatly improving the rolling efficiency. (2) Proved a variety of factors on the lateral force of the law. The larger the deflection angle of the small roll is, the larger the rolling reduction and the higher the rolling speed are, the larger the lateral force is. The reverse rolling is much larger than the lateral rolling force when rolling forward. In order to reduce the peak of the lateral force, so that it tends to be homogenized, the diameter or speed of the upper driving roller should be appropriately reduced. (3) A simplified formula for calculating the lateral force (F) of the small roller is derived from the theoretical analysis. A simple formula for determining the reasonable offset (e) of the small roller is also obtained from the conditions of ensuring the stability of the rolling. A certain range of offset is verified.
