Three-dimensional Analysis of Strip Rolling in a Large Production Mill

A 3-dimensional strip rolling analysis model considering strip lateral flow is developed in order order to overcome the disadvantages in the traditional theories. The distribution of specific rolling pressure, transverse stress, exit strip profile, edge drop and width spread are obtained by numerical calculations. Calculated examples under different kinds of rolling conditions conform to the reality, and results show that the developed 3-dimensional program is applicable for the narrow strip or wide strip, single stand or tandem mill.
