钢板自动测宽系统的开发与应用

为提高宽度测量精度,济钢中厚板厂2500产线在粗轧机前安装在线自动测宽系统,该系统主要由CCD器件、视频自动增益控制器、图像采集卡、工控计算机等组成。系统应用后,可实时测量轧制过程中钢板宽度,便于随时调整压下量,提高了长宽定尺板合格率,成品切边放尺量减少了4 mm,产品改判率降低0.02%。

To improve the width measurement precision, the on-line automatic measurement system was installed in front of roughing mill in medium and heavy plate mill on 2500 production line of Jinan Steel. The composition of the system mainly consists of a CCD device, video automatic gain controller, image acquisition card, industrial control compute, etc. After the application of the system, it could measure the width of plate steel in the process of rolling at any time, and could adjust the reduction of mill rolling easily at any time, it improved the qualified rate of length to width scale plate. The finished cutting edge residue quantity was reduced by 4 mm, and reduced the revision rate of 0.02% products.
