用正交实验方法对影响板带材轧制头部翘曲的因素进行了铅板轧制实验研究。影响因素有上下轧辊直径比、压下率、导入角和轧辊转速。正交实验是L25(45)，研究表明：辊径比对头部翘曲影响最大，导入角的影响次之，轧辊转速的影响最小，各种因素的影响趋势变化呈现了不同的规律。实验轧机控轧6 mm铅板头部翘曲的最佳工艺参数为上下轧辊直径比1∶1，压下率5%，导入角-3°，轧辊转速164 r/min。
The factors affecting end curl of plate and sheet in rolling process were researched by the cross experiment, which include the upper roll diameter, the lower roll diameter, reduction, angle of entrance and velocity of roll rotation. The cross experiment was designed with L25(45). The result indicates that the ratio of roll diameter has the most important effect on the end curl, the angle of entrance is in the second place, the roll rotational velocity has the weakest effect. The best technology parameters of rolling 6 mm Pb for experiment milli are 130/130 roll diameter, eduction 5%, angle of entrance -3°, roll rotational velocity 164 rpm.
