Traditional laboratory lubrication tests involve measurement of neat oils. To achieve increased levels of test severity, such tests are often carried out at high temperatures and prolonged durations. However, unrealistic levels of lubricant degradation and wear can occur during these tests. Moreover, steel rolling is done with emulsions and not with neat oils. To better approach the situation in the field, laboratory lubrication tests were developed for emulsions. The emulsions are kept at normal operational temperatures. Realistic in-contact residence times and levels of severity are achieved by mimicking frictional power intensities and flash temperatures for typical cold rolling or tinplate mills. The viability of the method is illustrated by a number of field cases. © 2014 by AIST.

In order to account for the plastic surface deformation occurring in cold rolling, a novel, 3-D Stribeck curve is proposed. This curve is characterized by three 'anchor points', which represent surface chemistry and two aspects of lubricant rheology. Each anchor point can be measured in the laboratory but requires well-defined conditions, while a separate strategy is proposed for assessing ep/aw performance. Two operational numbers define the lubrication regime. They represent film formation in the inlet zone and in-bite film formation facilitated by plastic surface deformation. The ideas behind the 3-D Stribeck curve are used in a more targeted lubricant development.
