八钢3 500 mm中厚板轧机实现全线全自动生产,其中,基础自动化速度控制技术至关重要。主要描述如何通过金属秒流量相等原理进行设定速度分配、使用最优位置控制曲线进行停车位置计算和翘扣头控制等方法实现生产线速度控制运行稳定和可靠的目的。通过长时间的连续生产证明速度控制技术效果良好,且多项控制手段可推广于热轧。 Bayi Steel 3 500 mm plate mill to achieve full automatic production line, of which the basic automation speed control technology is essential. Mainly describes how to set the speed distribution by the principle of equal flow of metal second, and uses the optimal position control curve to calculate the parking position and control the head of the head and so on to achieve the goal of stable and reliable operation of the production line speed control. Through a long period of continuous production proved speed control technology works well, and a number of control measures can be extended to hot-rolled.
