    • A method is provided for controlling interstand tension by roll gap adjustment to reduce gage variations caused by unplanned rolling velocity changes wherein a signal proportional to the tension changes produced by deviations from the desired speed ratio of adjacent stands (1,2) is used to modify the conventional tension error signal before the latter signal is used to control roll gap thereby discriminating between tension changes caused by mill stand or strip physical changes, which it corrects, and tension changes caused by unplanned speed disturbances, which it ignores instead of maintaining constant tension. The resulting system exhibits improved tolerance for imperfect stand speed control.
    • 提供了一种用于通过辊间隙调节来控制台架间张力的方法,以减少由计划外滚动速度变化引起的量具变化,其中与由相邻机架(1,2)的期望速度比的偏差产生的张力变化成正比的信号被用于修改 在后一信号之前的常规张力误差信号用于控制辊间隙,从而区分由其校正的轧机机架或带状物理变化引起的张力变化以及由计划外速度干扰引起的张力变化,其忽略而不是保持恒定的张力 。 所得到的系统对于不完美的立场速度控制表现出改进的公差。

    • A system for creating an image of the surface contours of a metal workpiece (10), such as a continuous cast slab, is provided including a sheet of single frequency planar light (28) directed to strike a surface (12) of the workpiece (10), and a video camera (30) positioned to view the surface (12) where the light strikes, such that when the surface (12) of the workpiece (10) is flat, a straight line is sensed by the video camera (30), when the surface (12) is irregular, the video camera (30) senses a nonlinear line, the video camera (30) creates a two dimensional image of the sensed light and supplies this signal to a processor (34), which then creates an image of the workpiece (10) which can be displayed by a video monitor (36, 39) and/or a printer (38). The processor (34) extracts a variety of quantitative parameter values from the images.
    • 提供了一种用于创建金属工件(10)的表面轮廓的图像的系统,例如连续铸造的板坯,其包括指向冲击工件的表面(12)的单个频率平面光(28)的片材 10),以及摄像机(30),定位成观察光照射的表面(12),使得当工件(10)的表面(12)是平坦的时,由摄像机感测到直线 如图30所示,当表面(12)不规则时,摄像机(30)感测到非线性,摄像机(30)产生感测光的二维图像,并将该信号提供给处理器(34),处理器 然后创建可由视频监视器(36,39)和/或打印机(38)显示的工件(10)的图像。 处理器(34)从图像中提取各种定量参数值。
