and high pressure hydraulic systems control the rolls and other mill equipment. Rolling fluids on aluminum mills include water, water oil emulsions, kerosene and mineral oil. Heat from hotrolled aluminum and frictional heat generated by the rolling process cause the rolling fluid to evaporate. Some also splashes off the moving rolls.
