摘要
针对以往连退生产过程中对带材板形的演变过程只能定性分析、无法定量预报与控制的问题,首先在引入段内板形与段外板形概念的基础上,充分结合连退机组的设备与工艺特点,建立了一套适合于连退机组退火过程的板形预报模型,并以特定连退机组的典型规格产品为例定量分析了段内外板形的演变规律;随后以带材在段内整体板形最好、段内最大板形最小、机组出口板形与目标板形差距最小为目标,带材在通板过程中不出现热瓢曲、跑偏以及震动为约束条件,从张力优化设定入手,提出一套适合于连退过程的板形在线综合控制技术,并将其推广应用到生产实践,取得了良好的使用效果,有效提高了机组的通板稳定性与出口板形控制精度,具有进一步推广应用的价值。
In allusion to the issue that the evolution of strip shape can only be qualitatively analyzed and can＇t be quantitatively predicted and controlled in continuous annealing process,firstly on the base of putting forward the conception of in-section strip shape and out-section strip shape,fully combined with mechanical and technological characters of continuous annealing process,a set of shape prediction model be suitable for continuous annealing process was built in this paper,and the evolution rule of in-section strip shape and out-section strip shape were quantitatively analysed in an example of the typical specifications product of a specific continuous annealing process. targeting the best whole shapes in section,the minimum in-section shapes and the minimum shape difference between unit exit and the goal,in condition of not occurring of buckling,deviation and vibration,according to the tension optimal setting,a set of comprehensive control technology be suitable for continuous annealing process was put forward,and promoted in production practical,which achieved good results and improved the strip conveying stability and the accuracy of exit shape control,good potential of popularization and application can be realized.
