Metals such as aluminum, brass, copper etc., are rolled
into sheets or other
shapes in continuous rolling mills designed somewhat like those found in steel mills. Modern mills use circulating oils to
lubricate the gear drives, pinion stands, and journal bearings. Either mild EP or
MP gear oils of a noncorrosive nature can
be employed in such service. The
grade of oil
will depend upon the speeds of the gears
and may vary
from an SAE 80 to
an SAE 140. In screw down
equipment either of the above type
of oils or a straight mineral
oil can be
used. Where any of the above
drives are through open gears, a residual type
of gear oil containing
a rust inhibitor
and having a viscosity of 1000 to
2000 SUS at 210 degree F should
prove satisfactory. The best
practice is to apply
such a lubricant automatically so as
to insure a coating on the
gears at all times.
