Method and device for controlling speed of steel plate after tailing-out

The invention discloses a method and device for controlling the speed of a steel plate after tailing-out. A speed reduction point is adjusted on line according to the actual speed and position of the steel plate, on the premise of ensuring that the biting speed vb can be met, the acceleration process of a long plate is prolonged, the running speed of the long plate is increased, and the speed of conveying the steel plate to a pre-straightening machine is increased, so that the efficiency of a steel rolling process is improved. According to the method and device for controlling the speed of the steel plate after tailing-out, the problem that the acceleration stage of the long plate is insufficient is solved, the conveying speed of the long plate after tailing-out of a finishing mill is accelerated, the production efficiency is improved, the purpose of improving the yield is achieved, and good popularization performance is achieved. 本申请公开了一种抛钢后钢板速度的控制方法及装置，根据钢板实际速度与位置进行在线调节降速点，在确保可满足咬入速度vb前提下，延长长板的加速过程，提高了长板的运行
