摘 要：In order to account for the plastic surface deformation occurring in cold rolling,a novel,3-D Stribeck curve is *** curve is characterised by three’anchor points’which represent（1）the friction in the boundary regime,（2）the friction in the elastohydrodynamic regime,and（3）the friction experienced in a thin lubricant *** operational numbers define the lubrication regime,representing（1）film formation in the inlet zone,governed among others by the process speed and（2）in-bite film formation facilitated by plastic surface deformation,governed among others by the sliding speed in the *** in the rolling process can be influenced by any of the 3 anchor points and 2 film formation mechanisms,all of which are influenced by the lubricant *** ideas behind the 3-D Stribeck curve can be used in a more targeted lubricant *** 3-D Stribeck curve can be measured in the laboratory,preferably for *** test methods were developed to investigate boundary lubrication of emulsions under severe conditions,mimicking frictional power intensity and flash temperatures in the roll *** correlations are found with performance in a pilot mill and a production mill.
