Two systems for on-line oil film and surface roughness measurement for strip steel production

摘要

Oil layer and surface roughness of steel strip are measured on line with equipment that has been adapted to withstand the severe environment of a cold rolling mill. The system ensures the effective lubrication of the strip and it displays roughness data all along the coil. This makes it possible to optimize the rolling process on-line and it affords comprehensive information on the strip properties.
