The Role Of Rolling Lubrication Cleanliness On The Surface Quality Of Cold RolledAluminum Sheets

摘要

In aluminum cold rolling, filtration efficiency of rolling oil is dependant on the combinations of filtermedias as well as the other parameters of rolling such as rolling temperature, lubricant type, ratio, thetype of alloy, thickness and deformation ratio.In this study, a series of on line particle size measurements has been made by taking the effect offilter medias, filter time, rolling speed as well as the thickness and the composition of the sheetsrolled into account to monitor the filter efficiency during rolling. The cleanliness of sheets rolled hasbeen measured and Scanning Electron Microscopy (SEM) has been used to see the surface of thesheets.The analyses have been showed that filter efficiency and rolling performance is a strongly depend onthe filter media, the quantity and size of the particles which are produced during cold rolling ofaluminum.
