Advertorial on behalf of Decalub Extra clean wire at high speed
The BHW wire cleaning system is used
in the most demanding applications,
allowing extreme high cleaning speed,
with all carbon steel wires (including
0.90%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 upon severe conditions resulting
in increased heat and burned lubricant
tightly bound to the wire surface and
embedded in micro-cavities.
The BHW system provides the ultimate
combination of simplicity and
effectiveness: Acid-free, caustic-free,
without ultrasonic and chemicals.
Economical and environmentally friendly,
this completely ‘green’ system provides
significant process savings in production
of clean H/C and L/C wires.
The BHW system incorporates new
technology which enables normal plant
cold water to be converted into the
most unique “micro-abrading liquid”
agent used for cleaning of dry 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 brush bristles providing
hydro dynamic cavitations at bristles/
wire interface 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.
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 2.6 mm
(0.102") drawn wire is cleaned in-line at 12
m/s (2,400 ft/min) with 4 or 5 x BHW units,
obtaining an extra clean wire, enabling
direct galvanising and other metallic or
plastic coatings.
