过去,在轧制过程中,带钢宽度的测量以及带钢位置的控制采用接触式仪器,缺点是机械磨损严重,有碰撞的危险和维修工作量大。因此,英国钢铁公司与集成光学器材有限公司(IPL-IntegrafedPhotomatrix Ltd.)联合开发出一种采用线性扫描光学原理,价格低廉,用于带钢宽度测量、对中和检查的非接触式的系统。此系统用于冷轧带钢生产完成如下功能:宽度测量;带钢对中;针孔检查;边沿裂纹检查。
In the past, in the rolling process, strip width measurement and strip position control using contact instruments, the disadvantage is the mechanical wear and tear, the risk of collision and maintenance workload. As a result, British Steel and IPL-Integrafed Photomatrix Ltd. jointly developed a non-contact system that uses linear scanning optics, is inexpensive, is used for strip width measurement, and for centering inspection. This system is used for cold-rolled strip steel production to complete the following functions: width measurement; strip centering; pinhole inspection; edge crack inspection.
