Flat Rolling Process - an overview | ScienceDirect …

The flat rolling process is usually taken to be essentially two-dimensional in the sense that the width of the product does not change much during the pass when compared to thickness and length changes and this makes the assumption of plane-strain plastic flow 5 quite realistic. When one is to study roll bending and the attendant changes of the shape of the rolled metal in addition to the ...
