在板带轧机上,影响成品厚度精度的因素很多,如坯料的厚差、硬度及轧机和辊系的刚度、精度,特别是支承辊偏心的影响,更有重要的作用。据资料报导,在五机架冷轧机上,0.6～0.7mm的轧件,在第一次冷轧中,引起轧件厚度不均匀的原因来自支承辊;在第二次冷轧中,大约平均离差标准之半仍是支承辊和颤振所致,而这些在厚度标准离差的 In the strip mill, the impact of the thickness of the finished product of many factors, such as the thickness of the blank, hardness and mill and roller system stiffness, accuracy, especially the impact of eccentric roller, more important role. According to statistics, in the five-stand cold rolling mill, 0.6 ~ 0.7mm rolling in the first cold rolling, causing the rolling thickness unevenness of the reasons from the backup roller; in the second cold rolling, about the average Half of the standard deviations are still due to back-up rolls and flutter, and these are standard deviations in thickness
