Rolling processes 5-1 introduction Rolling is the process of reducing the thickness or changing the cross section Figure (5-2) illustrates the sequence of steps in a steel rolling mill to show the variety of products made. Similar steps occur in other basic metal industries. by shape rolling include construction shapes such as I-beams
The flatness is defined in I-units One I-unit corresponds to a difference in length of 10 µm per meter of strip length. The levelness describes the topography of the strip surface i.e. the deviations in height observed when the strip lies on a level surface. The measuring rollers and the VIP08 optical system from Vollmer measure the flatness.
