In cold rolling process of thin strip,flatness control is an integral component of modern mill.In this paper,two typical flatness control systems,pattern recognition flatness control system and multivariable flatness control,are discussed in detail.It is found that the latter has more effective applications.In this study,the finite element method ( FEM) models of its core parameters,flatness actuator efficiency,are established.Influencing factors,such as the rolling force,bending force as well as the tilting force are discussed.Adjustment strategies are proposed for flatness defects.The results demonstrate that the control strategies can reduce flatness error and improve the flatness quality.

Controlling the friction in the rolling bite is important to the cold rolling of metal strips.The main difficulty is that the strip surface deformation in a rolling process is associated with mixed lu
First,the development of the studies in cold sheet rolling with O/W emulsion in Japan from 1970 to 1990 is reviewed.Second,the mechanism of film formation in EHL contact region is reviewed.Third,the r
Profile and flatness is one of the most important quality indexes for wide strip.To the high quality steel,the downstream processes have higher requirement to its profile and flatness.Therefore,it is
In the hot rolling process,certain asymmetrical rolling conditions may cause transversal thickness differences in the slab and deviations in the rolling direction from the center line,which are called
In order to improve the accuracy of roll flattening calculation based on semi - infinite body model,a more accurate roll flattening model is proposed in this paper,which is derived based on boundary i
在单机架冷轧机厚度控制系统中,非稳态轧制非常容易造成厚度精度不稳定,研究表明导致带材厚度波动的两个关键因素是轧制模型与AGC模型精度,而轧制模型精度与AGC精度有着非常紧密的关系,根据实际经验及理论分析只要确保设定轧制力与实际轧制力偏差在5％以内及AGC响应速度足够快,就能保证带材的厚度精度足够好.但是在实践中要保证轧制模型始终有如此高的精度是一件非常困难的事,往往依靠操作工的经验来提高预设定的精
