摘要
通过对宝钢1420冷轧轧制力模型的理论计算和控制方法的分析,认为采用沿高度应力均匀分布的平面假设将带来比较大的误差。对延伸率控制系统的完善和延伸率控制系统的研究,提出了改善该控制系统的设想,将带材的力学性能与外形质量结合来进行调整,经过现场试验与理论研究,通过轧制力设定,既能保证延伸率精度又可以满足板形的要求,在1420冷轧平整机上进行试验,验证了模型的正确性,表明建立的计算模型可提高轧件断面形状和板形的计算精度。
During skin rolling of comparatively thick strip plastic deformation quantity is very small, so mat me aelormation in the high direction is uneven. The theoretical calculation and control method of the skin pass roiling force model for Baosteel 1420 cold rolling mill are analyzed. Based on the introduction of combination control objective function of the shape and mechanical property, the mechanical property and the outline quality are first combined into an uniform object. Through the coordinated set of the roiling pressure, the research on the existing elongation rate control system and its improvement program is introduced. Ideas of perfecting system have been advanced both the accuracy of the elongation percentage is assured. Apply it practically well to improve skin precision for Baosteel 1420 skin mill.
