is oil used in hot- and cold-rolling of ferrous and
non-ferrous metals to facilitate feed of the metal between the work rolls,
improve the plastic deformation of the metal, conduct heat from the metal,
and extend the life of the work rolls. Because of the pressures involved, a
rolling oil may be compounded (see
compounded oil) or contain
EP additives. In hot rolling,
the oil may also be emulsifiable (see
emulsion).
Rolling oils have water dispersible cold rolling
oil composition for aluminum and aluminum-containing alloys comprising (a)
one or more lube oil components selected from mineral oils, higher fatty
alcohols, higher fatty esters and higher
fatty acids, and (b) a specific water soluble
cationic or amphoteric polymer compound. The
composition provides a cold rolling lubricant which possesses excellent
cooling capability, rolling lubricity and circulation stability, and can be
readily controlled in operation.
