1 Introduction
2 Formula Derivation Based on Elastic Half Plane Theory
3 Modification of Roll Flattening Model
3.1 Finite Element Simulation of Roll Flattening
Flattening size | The centre (minimum) (mm) | The end (maximum) (mm) |
---|---|---|
Based on plane assumption | 0.129 | 0.146 |
Calculated by FEM | 0.128 | 0.152 |
