宽带钢粗轧机控制系统升级改造的研究与应用

Transformation of Control System of Roughing Mill for Wide Strip

莱钢原有的宽带钢生产线粗轧机基础自动化控制系统已不能满足目前带钢产品的质量要求,系统升级势在必行。改造后的系统控制模型在粗轧规格道次间修正计算、轧制模型等方面都有多项技术创新,并开发了多种模型的自学习策略,显著提高了钢坯宽度控制、轧制力预报、辊缝设定等模型的控制精度。

With the development of production level ,the original control system of roughing mill is unable to meet the requirements of the product quality of strip steel .This paper introduced the upgrading and transformation of the control system .The upgraded system is of a number of technical innovation in the pass correction calculation of roughing specifications ,the rolling model ,and the development of the learning strategies for various models ,can significantly improves the slab width control ,the prediction of rolling force ,the setting precision of roll gap .
