An Investigation of the Process Parameters for Calibre Rolling Using a Complex Analytical Model

Calibre rolling is a complex 3D boundary problem. Several analytical methods were applied to analyse this topic and some progress was achieved. However, it was difficult to include both analytical precision and CPU time saving in the calibre rolling analysis. In this paper, the simplicity of the 3D slab method and the precision of 3D rigid-plastic finite element method were combined to develop a complex analytical model. This model can rapidly simulate calibre rolling and the results obtained match well with the experimental ones. A complex analytical model can be used for discussing the influence of each process parameter on calibre rolling, which can assist the efficient process design of calibre rolling and find the optimal combination of each process parameter.
