摘要
为了提高板形控制精度和自动化程度,结合我国某厂UCM可逆轧机生产实际情况,基于轧辊弹性变形原理建立了影响函数法工作辊弯辊力寻优机制。根据不同带钢宽度、变形抗力、入口厚度、压下率和入口凸度以及轧辊半径计算与目标出口凸度对应的最佳弯辊力,将计算结果进行逐步回归分析,建立了板形设定模型,该模型计算值与影响函数法计算值之差在±20kN内。
For increasing shape control accuracy and automation level, the influence function method optimized mechanism of work roll bending force were obtained base on roll elastic deformation theory according with do- mestic UCM mill production practice. The optimized bending force was calculated base on vary strip width, deformation resistance, entry thickness, draft, entry crown and roller radius. The shape preset mathematic model was established by regression analysis. The calculation difference between mathematic model and influ- ence function method is located in ±20kN.
