二十辊轧机轧制极薄带的板形控制
Plate shape control of ultra thin strip rolling for 20-high mill
摘要
Abstract
To improve the accuracy of roll flattening calculation for 20-high mill, a new and more accurate roll flattening model was proposed. In this model, the roll barrel was considered as a finite length semi-infinite body. Based on the boundary integral equation method, an accurate roll flattening model was established. Based on the new roll flattening model, coupled with roll bending model, strip plastic deformation model, a new and more accurate plate control model for 20-high mill was established. Based on the new model, for the particularly thin strip rolling process, the effects of taper angle and axial shift of the first intermediate roll were analyzed, and the accuracy of the new model was certified by rolling test. The results show that the taper angle and axial shift of the first intermediate roll have greater influence on the shape control, and small changes in the shape of the roll gap will cause great changes of flatness.关键词
