Strip Rolling - an overview | ScienceDirect Topics
In the second case, the compression of the strip during the rolling pass is referred to as "homogeneous compression". Schey (2000) differentiates between the two possibilities, depending on the magnitude of the ratio of the average strip thickness in the pass, h ave = 0.5 (h entry + h exit), and the length of the contact, L = R ′ Δ h, where R ′ is the radius of the flattened but still ...
