Lubricant rheology in real conditions: measurements and confrontation with a ball/disk contact
Résumé
During the cold rolling of metal alloy sheets, the control of lubrication constitutes one of the major industrial problems. The aim of the study reported in this article concerns the rheological characterization of two industrial lubricants, under conditions close to those met in rolling. The application of EHD models then allows to calculate the lubricant film thickness, which is compared to the values measured by interferometry in a ball/disk contact.
