engineer the surface texture on the work roll to give
the best combination of features for both the sheet
producer and sheet user.
Previous Investigations
During the rolling process the transfer of the Ra and
Rpc from the work roll to the rolled sheet are two of
the two main measures of the work roll performance
in addition to the useable campaign life of the work
roll. Other attributes such as the generation of “mill
fines” during the rolling process and the retention of
the oil on the sheet, applied after rolling, during
transport and storage.
The forming process considers such factors as
formability, coefficient of friction, and resistance to
“scoring” and “galling” as important performance
measures. These factors are primarily influenced by
the rolled sheet surface roughness Ra and the
surface topography described by the Rpc and also
the number closed voids on the sheet surface.
Previous investigations of sheet steel surface
topography and the influence on the forming of
automotive panels concluded that a texture
comprising "many peaks and valleys" with a Ra in the
range of 1.4 - 2.0 um provided good forming
performance. (2) It also showed that as the surface
roughness Ra is reduced below 0.8 then “scoring” is
likely to occur and if the roughness is further
reduced to 0.5 um then “scoring” increases
significantly.
Formability is also considered to improve with
increased peak density, up to a limit when the
