COLD ROLLING OIL PERFORMANCE-A COMPARISON BETWEEN LABORATORY ROLLING MILL AND DISK MACHINE

Abstract

Five commercialoils have been evaluated in a laboratoJ:y rolling mill with multi -oasS experiments. '!he s1rips obtained have been eXCJ!\inedby SEM. '!he,sane lubricants were studiedby our technique (2) in 1111s18r disc machine and the discs eXCJ!\inedby SEM. A comparison w~ then attempted between these data which showed that the simple disc machine test offers good possibility to evaluate the cold rolling oils
