Chapter 4 Surface finish and friction in cold metal rolling

2004-3-16  In practice both the roll and the strip surfaces are rough. In many rolling processes, the roll grinding process leads to a roll roughness with a pronounced lay, with asperities running along the rolling direction. This longitudinal roughness is in turn transferred to the strip. Isotropic roughness is also common, for example where the

Selection of Work Roll Diameter for Cold Rolling Mill*

in a batch-operated rolling mill and of the final stand in a tandem cold mill, the strip tension is sometimes greater on the entry side than on the exit side. In such circumstances examination of the forward slip should be necessary. (3) The tendency to the higher draft diminishes the forward slip.
