Control strategy and control model for an accelerate cooling control system of plates after rolling

摘要: 针对轧板厂原有冷却系统冷却能力弱的实际情况,为了提高产品质量和生产效率, 专门为轧板厂生产线设计了一套全新的轧后快速冷却系统.系统集成了多种先进的控制策略和控制模型,同时采用了西门子高性能控制器,实现了整个系统的全自动控制.现场应用结果表明,冷却系统功能完善,控制精度高,钢板性能得到了很大改善.

Abstract: In order to improve product quality and rolling efficiency, a new set of accelerate cooling system of plates after rolling was designed for the plate rolling mill of Wuhan Iron and Steel Corporation. The system integrated many kinds of advanced control strategies and control models. High performance controllers of Siemens were also applied in the system and fully automatic control was realized. The application results showed that the cooling system had integrated functions and good control precision, and product quality was improved greatly.
