Based on the influence function,an analytic model is developed for the elastic deformation of rolls so as to simulate the strip rolling process on 6-high single cold mill with the intention to investigate the effect of work roll shift on strip's edge drop.

A new configuration of work roll shifting device, which is not used at domestic plants yet, is described in the article in regarding to the construction and operational concept.

The temperature field and the thermal crown of work roll under shifting were calculated by the limited differential method The calculated results were analyzed and compared with the traditional rolling type It was the reference to study the strip shape under work roll shiftin

Some typical roll shapes available to vary roll gap through roll shifting in rolling process were analyzed comparatively,such as basic CVC roll,optimal CVC roll and SMART Crown roll in view of the shape design,axial load acting on the roll and no-load roll gap.

The spheres of application,advantages and disadvantages of flat and roller cross-wedge rolling schemes were introduced systematically.
