Development of closed loop feedback control system of plate flatness for six-high reversible rolling mill

对于高等级冷轧薄板的板形质量控制问题,本文在对六辊可逆轧机的设备组成、板形控制原理等进行分析基础上,对目标板形曲线制定、板形控制策略和板形反馈控制数学模型等进行了充分研究,并编制了六辊可逆轧机板形闭环反馈的二级系统监控软件,软件应用效果良好,同时本文研究成果可为同类型轧机的板形控制设计提供参考。

Aiming at the flatness quality control issue of high-grade cold-rolled sheet, the equipment compo- sition and the flatness control principle of the six-high reversible rolling mill have been analyzed in the text. The curve formulation of the target shape, the shape control strategy and control mathematical model of the shape control feedback have been fully studied. The secondary systemmonitoring software of plate-shaped closed-loop feedback for six-roller reversing rolling mill has been established. The effect of software applica- tion is good, and the research results can provide reference for the flatness control design of the same type rolling mill.
