1.引言 钢铁企业小型轧钢厂较多,一些轧钢厂具有飞剪系统,以便对轧制的钢材进行定尺剪切,以满足用户要求。轧材经飞剪到冷床采用双通道输送卸料方式,该系统能定尺剪切设备允许范围内各种直径的线棒材;并能很好地完成切头、定尺剪切、切尾的功能;也能使高速运行的线棒材准确地输送到冷床。整个系统由日本立石公司 OMRON SYSMACC200H可编程控制器和与之相配套的编 1. INTRODUCTION There are many small steel mills in the iron and steel industry. Some mills have a flying shear system to cut the rolled steel to meet user’s requirements. Rolling through the fly to the cooling bed using dual-channel transport unloading, the system can cut the length of the device within the limits of the wire rod of various diameters; and can well cut, cut to length, cut Tail function; also can make high-speed operation of the wire rods accurately transported to the cooling bed.
