低压轧制控制金属基材平坦度的系统和方法
摘要：
平坦度控制系统包括精整线的工作台、多个致动器、平坦度测量装置和控制器。工作台包括一对竖直对齐的工作辊。所述一对工作辊中的第一工作辊包括多个平坦度控制区，所述平坦度控制区被配置为向基材上的相应区域施加局部压力。每个致动器对应于多个平坦度控制区之一。平坦度测量装置被配置为测量基材的实际平坦度轮廓。控制器被配置为调节多个致动器，使得局部压力改变实际平坦度轮廓以在台的出口处实现期望的平坦度轮廓。当基材离开工作台时，基材的厚度和长度保持基本恒定。
摘要（英）：

A substrate (e.g., metal or non-metal sheet) can have multiple textures on a surface of the substrate. The various textures can be impressed or applied on the surface of the substrate by passing the substrate between multiple pairs of work rolls that each include at least one textured work roll for transferring a texture of the work roll onto the surface of the substrate. The pairs of work rolls apply the various textures on the surface of the substrate while maintaining a thickness of the substrate (e.g., with substantially no reduction in a thickness of the substrate). A single pass of the substrate between the pairs of work rolls can allow various different textures, patterns, or features to be applied to the surface of the substrate while the thickness of the substrate remains substantially constant.
