7. Shake the wire rope vigorously, broomed-out
end down, to remove any grit between the
wires or in the hemp center. Only air from the
cabinet supply is used to remove grit; do NOT
use any other source, because other sources
may be contaminated with oil or water.
8.
Remove the grit-siphon tube from the grit
supply, and air blast the wire rope to remove
the remaining grit.
NOTE: After grit blasting a total of 15 broomed-out
ends, drain off 10 pounds of used grit from the bottom
of the hopper and replace it with 10 pounds of new grit.
9.
Remove the tape from the wire rope.
10.
Prepare a solution and flux the wire rope.
Fluxing
For solution preparation and fluxing, the following
procedures are used:
1.
Heat
the
pre-mixed
solution
until
the
temperature is between 160 and 210°F, using
the
hotplate
provided.
Measure
the
temperature of the solution with the bimetallic
thermometer. Allow the solution to remain at
this temperature for 5 minutes, then remove it
from the hotplate and allow it to cool to room
temperature.
2.
Remove any scum or foreign matter from the
surface of the cooled solution with clean
napkins or wiping towels. Do NOT agitate the
solution during this operation.
3.
Carefully pour the clear, cooled solution into
another stainless steel container. Avoid pouring
any foreign matter into this container. If the
hot-air drying method is used, the solution can
be used cold. If the cable is to be dried by
natural air, use the procedures listed in step 4.
4.
Heat
the
clear
flux
solution
until
the
temperature
is
between
160
and
210°F.
Immerse wires carefully so the flux solution
does not enter the core of hemp-center-type
wire rope.
WARNING
Do NOT flux wire rope terminals.
5.
Immerse the grit-blasted wires in the solution
to within 1 inch of the top of the seizing for 5
minutes.
6.
Remove the wire rope from the solution, shake,
and turn the broomed end upright at once. Then
allow it to dry for 5 minutes. Any evidence of
rust on the wires after the flux-dry period will
necessitate refluxing.
