十五辊组合矫直机矫直模型研究

用几何分析和数值模拟相结合的方法,研究了中板采用十五辊组合矫直机矫直过程中的变形演化状况.研究结果表明,板材在十五辊组合矫直机矫直过程中弯曲变形和曲率演化有别于普通矫直机, 可以得到更高的薄板矫直精度.平行矫直技术和张力矫直技术是与组合矫直机辊系相适应的技术,它可以提高矫直的精度,同时消除负扭矩对矫直辊的影响,从而提高了矫直机的矫直材料强度能力范围.同时,提出一种矫直过程计算方法,采用这种方法所得计算值与模拟值、实测值基本一致.

Research of Leveling model of fifteen_roller combination leveler

Evolvement of plate in fifteen-roller combination leveler are studied in this paper using both analytic geometry and FEM.The results show that the bending deformation and curvature evolvement are different from those obtained by general leveler.The technologies of parallel leveling and tension leveling are adaptive to the roll system of combination leveler,which not only can improve leveling precision,but also can erase the influence of negative torque on leveling roll,thus improving the leveling strength capacity of leveling materials.Meanwhile,a new calculating method of leveling process was pointed out,whose results were basically consistent to those of experimental results.
