摘自《Trans. ISIJ》,1988,Vol. 28,NO. 2 日本神户钢铁公司加古川厂在其热轧精轧机组上安装了一套新的控制系统。该系统的每一台计算机都可以通过数据通道使用所有的存储数据,代替了人-机的交接作用。该系统的控制方法如下。 1. 该厚度控制系统由一台厚度测量AGC、一台监测AGC和一台X射线AGC(自动厚度控制)构成。另外还包括一个非干扰控制数模用于补偿弯曲力对产品的影响,以及一个载荷分配控制数模用以保持各机架间的允许平直度。为在各机架间保持一定的板带张力,引入了低惯性活套挑和交叉控制器。 2. 操作控制系统根据不同载荷对轧制过程进行动态修正,用光学传感器监测前一个板带的端头蛇
Adapted from “Trans. ISIJ”, 1988, Vol. 28, NO. 2 Kobelco, Kobe Steel, Japan installed a new control system on its hot-strip mill. Instead of a human-machine interface, every computer in the system can use all the stored data over the data channel. The system control method is as follows. 1. The thickness control system consists of a thickness measurement AGC, a monitoring AGC and an X-ray AGC (automatic thickness control). A non-intrusive control pattern is also included to compensate for the effects of bending forces on the product, as well as a load distribution control digital model to maintain allowable flatness between racks. In order to maintain a certain strip tension between the racks, the introduction of a low inertia looper pick and cross controller. 2. The operation control system dynamically modifies the rolling process according to different loads, monitors the previous snake with the optical sensor
