Effect of Three Types of Driving Modes of Rolling Mill with Six Rolls on the Friction Force between Rolls

Abstract

Three-dimensional finite element model of rolling mill with six rolls in a factory is modeled by nonlinear FEM software called ABAQUS. It is a three-dimensional elastic-plastic rolling model. It includes not only elastic-plastic deformation of strip but also the bending of roll system and flattening of rolls. It can describe the changes in friction force between rolls better. Conclusions are as follows. When the driving roll is the backup roll, friction force between the backup roll and the intermediate roll is easy to reach the maximum value, slipping phenomenon is easy to appear. When the driving roll is the intermediate roll, friction force between the intermediate roll and the work roll is easy to reach the maximum value, slipping phenomenon is easy to appear. When the driving roll is the work roll, the changes in frictional force between the rolls is smooth. Slipping phenomenon is not easy to appear.
