Wire & Cable ASIA – September/October 2007 67
There are currently four methods of
wire purification after scaling:
mechanical cleaning by brushing;
mechanical cleaning by jetting;
mechanical purification by peeling and
purification by using chemical aids.
However, Meier Technische Beratung
has emerged with a new development.
After breaking the scale the wire rod is
run through equipment in which six
or eight fast rotating cleaning units,
loaded with pads of steel-wool,
surround the surface and take off parts
of grain or dust.
The thin ropes of steel wool cause a
scraping effect on the surface of the
wire but without damaging it because
of the weakness of the pad which
adjusts itself to the surface, and the
surface of wire is smoothed in a very
soft way.
The cleaning units are positioned in
angles of 180° along the working
distance. This method gives a purified
surface and sets the wire in the best
condition for further working. There is
no necessity for passivation.
In spite of the plant costs, the operation
costs in total are very low: no brushes,
no tapes, no cutting tools, no acids,
only inexpensive pads of a special steel
wool. The rubbish can be recycled or
disposed as waste.
The physical dates are not affected
and the quality of the wire is equal to
the conditions after hot-rolling.
Additionally, the increasing temperature
while working causes relaxation to the
wire rod.

metal-clad wire and ribbon that
are a cost-effective alternative to
solid products for manufacturing
high-reliability connectors and
components are available from
Anomet Products.
To meet specific requirements,
Anomet precious metal clad wire
and ribbon can include platinum
for oxidation corrosion-resistance
and bio-compatibility; gold for
contact resistance and palla-
dium or silver, each clad to core
materials such as copper, Kovar®,
niobium,nickel-iron,molybdenum,
stainless steel, tantalum and
titanium.
Precious metal clad wire and
ribbon is offered in diameters of
0.05mm to 3.2mm and up to
25mm, respectively.
