西门子计算模型在承钢1780热连轧机的应用

The Applications of Siemens Computing Model ChengDe Iron & Steel 1780 Hot Rolling Mill

承钢1780热连轧生产线西门子计算模型,论述了在热连轧生产中从板坯未到达时的预计算模型到板坯到达后通过实测值对设定进行闭环控制的入口修正、自适应、后计算模型,通过对西门子计算模型的计算模式和原理的论述使我们了解复杂的热连轧生产控制中所需要的精确设定点是如何获得的,并且针对西门子计算模型的特点提出了维护方法,以便于我们更好的进行程序维护。

This article takes Siemens calculation model in 1780 HSM of Chengde Iron＆Steel Corp. by which it discusses the following items during continuous hot rolling： the pre-calculation model before slabs arrive, then after slabs arrive, the close loop control to the settings by measured values, including entry correction, self adaption and after-calculation model. Via addresses of Siemens calculation model patterns and principles, this article will lead us to know how to obtain the exact setting points in such complex hot rolling controlling. Meanwhile, it brings maintaining methods referring characteristics of Siemens calculation model, so that we will be able to maintain the programmer better.
