环件径向轧制是无缝环件最重要的生产工艺。最常见的工艺误差之一是径向轧制间隙内环的爬升。用传统的径向滚环机传感器，还不可能以任何方式检测环的爬升。为此，在LPS （Chair of Production Systems）的径向-轴向轧环机上安装了图像处理系统，该系统特别记录了环在径向轧制间隙中的侧面。本文论证了该智能图像处理系统在相当困难的环境下的基本测量能力，并给出了不同的步骤和实验选择，为系统的测量精度提供了可靠的信息。提出了用于环爬升高度检测的算法，并对算法的可重复性进行了检验和评价。一旦证明系统提供了可靠的结果，这项工作就会根据目前的技术水平使用不同的参数来影响环的爬升。在分数因子设计中测试了这些参数影响环爬升的强度。这些知识用于设计滚动策略，以避免环的爬升。基于这些策略，本文介绍了整个轧制过程中静态参数的首次实验。本文介绍了实现一个图像处理系统来确定环的爬升高度的必要步骤和实现方法。这最终实现了一个自动化系统，以避免环在径向轴向轧制的早期爬升。
Radial-axial ring rolling is the most important production process for seamless rings. One of the most occurring process errors is the climbing of a ring in the radial rolling gap. With the conventional sensors of a radial-axial ring rolling machine, it has not yet been possible to detect a ring’s climbing in any way. For this purpose, an image processing system was installed at the radial-axial ring rolling machine of the LPS (Chair of Production Systems) which particularly records the side of a ring in the radial rolling gap.This paper proves the basic measuring capability of this intelligent image processing system in the rather difficult setting and presents different steps and experiments chosen to give reliable information on the system’s measurement accuracy. Furthermore the used algorithm to detect the climbing height of rings is presented and the degree of repeatability gets examined and evaluated. Once it is proven that the system delivers reliable results, this work uses different parameters based on the state of the art to affect the climbing of a ring. The intensity with which these parameters affect a ring’s climbing is tested in a fractional factorial design. This knowledge is used to design rolling strategies which avoid a climbing of the ring. Based on these strategies, this work introduces first experiments with static parameters during the entire rolling process.This paper shows the necessary steps and the ways these are realized to implement an image processing system to determine a ring’s climbing height. This finally serves to implement an automated system to avoid a ring’s climbing at an early stage in radial-axial ring rolling.
