THE USE OF A PILOT MILL FOR DEVELOPMENT OF LUBRICANTS FOR ALUMINUM HOT ROLLING

摘要

In this presentation Quaker's new pilot mill is introduced. The mill is designed for, among others, aluminum hot and cold rolling. Trial protocols for aluminum rolling will be discussed, as well as some results. The pilot mill can be utilized to develop new lubricant concepts, study emulsion properties and investigate new raw materials. The pilot mill is also used for validation of existing laboratory (tribology) test methods Aluminum hot rolling pilot mill trials were carried out to investigate the effect of lubricant type and emulsion condition Three different lubricants were trialed and roll forces compared. Trials were done with the fresh emulsion and with the emulsion after 1 week ageing. Furthermore, the effect of addition of a phosphorus-based extreme pressure additive to the (aged) emulsion was investigated. After the trials the surface texture was investigated with the electron microscope, allowing tentative conclusions on the lubrication mechanism.
