Analysis of strip rolling 1 NPTEL
Consider the rolling of a strip of initial thickness h o, between a pair of rolls of radius R. The rolls are rotating in same direction. The strip is reduced in thickness to h f with width of the strip assumed to remain constant during rolling – because width is much larger than thickness. Flat rolling is a plane strain compression process.
