摘　　要：给出现代轮鼓式飞剪的工作过程,并据此推导出其运行控制方法。该方法将飞剪控制过程分为加速运行、切点前、切点后和制动4个阶段,针对不同阶段的特点,分别推导出3闭环控制系统的加速度、速度和剪刃位置的设定依据。还给出了某钢厂采用该飞剪控制方法的电控系统框图。实践表明,此方法可广泛应用于热轧带钢、棒材、高线和处理线的飞剪控制。It deduced that the modern wheel-drum type flying shear＇s motion control method according with the given process of it. The method divided the process into four parts as acceleration, former cutting point, rear cutting point and brake. From which, the laws of the set point of acceleration, speed and knife position in triple closed loop were derived. Furthermore, a real electronic control system about this shear was presented. Applications of this flying shear show that it can be used on the control of flying shear of all kinds of band steel hot mill, claval steel hot mill, high speed ware hot mill and processing line.
