    • The invention relates to a process for cropping the head of self-luminous rolled material, especially metal strips when it passes a rolling train. A line scanning camera is used for detecting the shape of the head by repeatedly generating optical images of the rolled material immediately downstream of the last roughing stand. The distance separating the cutting line from the beginning of the head is determined in accordance with the shape of the head. Immediately upstream a pair of shears the velocity and the beginning of the head are detected. A control signal for the shears is generated in accordance with the signals for the beginning of the head and for its velocity and with the distance of the cutting line from the beginning of the head. In order to detect the edges of the rolled material from the beginning of measurement even under wide variations of the radiation intensity the exposure time of the line scanning camera is controlled by a radiation-intensity measuring device in the sense of obtaining an optimum exposure in respect of the edges of the rolled material.
    • 本发明涉及一种自动发光轧制材料的头部的切割方法,特别是当通过轧制列车时的金属带材。 行扫描照相机用于通过在最后一个粗轧机的紧下游重复产生轧制材料的光学图像来检测头的形状。 根据头部的形状确定切割线与头部开始处的距离。 在上游一对剪切的速度和头部的开始被检测。 根据头部开始的信号和其速度以及切割线距离头部的开始距离产生用于剪切的控制信号。 为了即使在宽的辐射强度的变化下也可以从测量开始时检测轧制材料的边缘,因此线扫描照相机的曝光时间由辐射强度测量装置控制,从而在获得最佳曝光方面 的轧制材料的边缘。
