目前在板带轧制生产中,重要的新技术和研究项目之一,是控制和改善板带钢形状(平直度)和横向厚度差,并使之与纵向厚度自动控制系统(AGC)联结在一起,进行综合自动控制,以得到高质量的板带钢成品,相应地提高产量。而在板带轧机上安装的液压弯辊系统就是有效实现这种控制的新装置。影响板带钢形状和厚度差的主要因素是:轧辊的弹性弯曲(即挠度)、轧辊压扁的不均匀分布、轧辊的不均匀热膨胀和磨损以
At present, one of the important new technologies and research projects in the strip rolling production is to control and improve the difference between the strip shape (flatness) and the transverse thickness and to make it to be linked with the AGC Together, a comprehensive automatic control, in order to get high-quality sheet steel products, the corresponding increase in output. The hydraulic bending system installed on the strip mills is a new device for effective control. The main factors affecting the strip shape and thickness difference are: elastic bending of the roll (ie, deflection), uneven distribution of the roll crush, uneven thermal expansion and wear of the roll to
