A Comparison between Full-Film and Mixed-Film Lubrication of Cold Strip Rolling

摘要

Nearly most of industries use a product of metal forming processes. The cold rolling is a major metal forming procedures used to make sheets of steel, aluminum and other ductile metals. The rolling is always lubricated with a kind of lubricant and the product quality, energy consumption and production speed is largely affected by the type of lubricant and most importantly the regime of lubrication. Since mass production is always important for cold rolling, speed of rolls and strips has to be high enough and the roll forces are considerably large values, therefore, the regime of lubrication might change between full-film and mixed-film type. In the present study, a comparison between these two kind of lubrication is presented for rolling of strips.
