2design calculations are done on the basis of a limiting strain that must not be exceeded. it should be noted that in cases of nonlinear deformation behavior, there is a difference between operating, for example, at 80 of the yield strain and operating at 80 of the yield stress. different values are obtained as depicted in figure 5.4.
It shows that, unreasonable design parameters will lead to the continuity degradation, that is, the high-order geometric continuity, i.e. g2, in the plane and profile may degrade to the low ...
8when rolling parts this way to some desired shape and tolerance, several passes might be required with roll adjustments necessary after each pass. this is relatively slow and requires considerable skill on the operators part. the two roll principal. the two roll principle method is comprised of a steel top roll and a urethane bottom roll.
0and mass ow in hot rolling mills can be satised by proper control of the strip tension and looper angle. figure 1 shows the tension and looper control in a typical nishing mill. traditionally, looper angle control has been per-formed by changing the rotating speed of a main motor but there has been no tension feedba.

John g. lenard, in primer on flat rolling second edition, 2014. 3.5 friction and wear. work rolls in hot strip mills wear due to friction between the roll surface and hot strip. back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill.
