The BHW wire cleaning system
is used in the most demanding
applications, allowing the highest
cleaning speed, with all carbon steel
wires (including 0.85%C), mechanically
descaled or acid cleaned, bare or
pre-coated, drawn with calcium or
sodium lubricants.
The BHW system is particularly
recommended for cleaning
applications in which a conventional
process is inappropriate, especially
with wires drawn in severe conditions
resulting in increased heat and burnt
lubricant tightly bound to the wire
surface and embedded in micro
cavities.
The BHW system incorporates new
technology which enables normal plant
water to be converted into the most
unique “micro-abrading liquid” agent
used for cleaning of drawn wire, in-line,
at high speed, at virtually zero energy
consumption, providing extra-clean
wire.
Basically, it is a sensitive multi-layer
displace/fine scrub/flush cleaning
system, benefiting from water
immersed high density ultra-fine
bristles performing as porous long-life
abrading pads that smoothly impact
wire surface separating lubricant
residue from base material, washing
away dispersed contaminants by
moving wire, exiting the unit very clean
of white-metal appearance.
At exit, the system can be fitted with
the PWC (Pressure Wet Cleaning) unit
for complete removal of residual
moisture film, providing wire polishing
for reflective appearance.
The BHW system provides the
ultimate combination of simplicity and
effectiveness: acid-free, caustic-free,
without ultrasonic, without chemicals.
Economical and environmentally
friendly, the system provides
significant energy and process
savings in production of clean H/C
and L/C wires.
The BHW system cleans drawn wire
from lubricant residue in applications
prior to heat treatment or coating,
including galvanising, annealing,
patenting, plating, welding (chain, mesh),
painting, plastic coating, Al or Cu
cladding etc. In a typical application, the
2.6mm (0.102") drawn wire is cleaned
in-line at 12m/s (2,400ft/min) with 3 to 5
x BHW units, obtaining a very clean wire,
enabling direct galvanising or other
metallic or plastic coatings.
