宽带钢冷连轧机综合耦合模型的分步解耦设计

Ordinal decoupling design of the complex coupling model for a wide strip tandem cold mill

对影响板形、板厚和张力的各种轧制因素进行了系统的理论分析,建立了冷连轧机综合耦合模型.针对耦合模型的特点提出分步解耦设计策略,相对于常规解耦设计可明显简化解耦过程,并给出各解耦环节的简化方案以利于实际工程应用.基于某1250mm八辊五机架冷连轧机第1机架的实际参数,采用Matlab/Simulink工具对简化后的分步解耦系统进行分析,仿真结果表明其可有效消除轧制过程中板形、板厚和张力控制之间的耦合影响关系.

A complex coupling model for wide strip tandem cold mills was established based on systematic analysis on the factors affecting on shape, gauge and tension. Aiming at the characteristics of the model, ordinal decoupling design was put forward which could simplify decoupling process more explicitly than normal decoupling design, and the simplified method of decoupling channels was given for practical application. Based on actual rolling parameters of the first stand of a 1250 mm 8-high 5-stand tandem cold mill, the ordinal decoupling system after simplified was analyzed by Matlab/Simulink tools, and the results show its decoupling effectiveness.
