Abstract:
The cold strip rolling process on a 4-h mill is studied by
coupling the 3 dimensional plasticity deformation of the strip
with the elastic deformation of the rolls. On the conditions of
that the width to thickness ratio of the strip is 660 and the
exit strip shapes are respectively edge wave, centre wave and
good, the computed results of the transverse distributions of
the roll gap, the rolling pressure, the interroll pressure, and
the front and back tension agree with the experimental results
well. The studing methods and the studied results are of great
importance to forming shape theory and guiding the development
of shape control technology.
