Modelling of Thin Strip Cold Rolling With Friction Variation by A 3-D Finite Element Method

Abstract

In this paper, the rolling of thin strip is simulated by a 3-D rigid plastic finite element method (FEM), which considers friction variation models. The calculated rolling pressure, spread and forward slip, taking into account a suitable friction variation model in the roll bite, are in good agreement with the experimental values. Based on the FE simulation, the calculated strip velocity at the exit of roll bite is obtained, and the effect of the friction variation on the shape and flatness of strip is presented, the characteristic of the snaking of strip is also described in this paper.
