Abstract

Edge-drop control enlarges the shape control theories and technologies. But compared to the profile and flatness control technology, the edge drop control is a developing topic. This paper analyze the influence of strip thickness, strip width, reduction ratio, friction coefficient and deformation resistance on the edge drop based on the elastic deformation of rolls and the three-dimensional plastic deformation of strip for UCMW cold rolling mill. The results will support the further research on the edge drop control for cold rolling mill.
