The multi-roll mills that are commonly used to produce the ultrathin strip are designed based on this theory. Fleck and Johnson [5, 6] considered that the plastic deformation occurs near the entrance and exit of the deformation zone during the ultrathin strip rolling.In the middle of the deformation zone, the strip does not reduce or slip relative to the rolls.

The angles show how much forming is being done at each pass. If end flare is a concern and you want a finish pass, consider adding two more passes to this 10-pass example. Pass No. 11 would unfold bend No. 1 to about 86 degrees, and pass No. 12 would re-form bend No. 1 to the finished angle of 90 degrees.
