一、引言近年来由于轧制技术的进步,诸如板厚自动控制系统、程序计算机系统等的采用,使平辊轧制材的质量大大提高,但控制带材整个宽度上厚度和平直度均匀性的技术问题看来尚未完全解决.为解决此问题,显然关键在于补偿轧制时的轧辊挠度.通常,补偿轧辊挠度的方法是:事先把辊身磨成凸形、液压弯辊、采用轧辊冷却剂,但控制量很有限,难于解决带材尺寸变化和材质变化所带来的问题.住友金属工业公司根据带钢轧制和轧辊制造的技术成就发展了一种新颖的轧辊凸度控制系统——住友轧辊凸度调整系统(VC调整系统).VC调整系统已经安装在各种二辊和四辊轧机上,用作带材板形和
I. INTRODUCTION In recent years, due to the progress of rolling technology, such as automatic control system of thickness and program computer system, the quality of flat rolled material has been greatly improved. However, the control of strip width and straightness uniformity Of the technical problems does not seem to have been fully resolved.To solve this problem, it is clear that the key is to compensate roll deflection when rolling.Generally, the method of compensation roll deflection is: pre-roll the body into a convex, hydraulic bending roll, roll cooling But the amount of control is very limited, it is difficult to solve the problems caused by strip size changes and material changes Sumitomo Metal Industries has developed a novel roll crown control system based on the technical achievements of strip rolling and roll manufacturing - - Sumitomo roll crown adjustment system (VC adjustment system) .VC adjustment system has been installed in a variety of two-roll and four-roll mill, as strip shape and
