rolled, cold rolled, intermediate annealed and in most cases grinded on the surface [2]. Flatness measuring – the flatness measuring roll On the exit side of the mill the strip is bent over a segmented roll, the flatness measuring roll. This roll measures the force on each segment and in this way the flatness of the strip can be decided.

The majority of cold and foil rolling operations use oil-based lubricants, although some mill systems can accommodate water-based alternatives. The base oil represents more than 90% of the total lubricant volume and acts as a solvent for the load bearing additives and a roll-cooling medium. The base oil viscosity has a significant effect on the ...
