Wire cleaning & treatment
May 2016 51
The BH-S is a green dry cleaning process
of great potential, used in-line in the
most demanding applications, allowing
high cleaning speed with all steel
wires (including 0.90%C), mechanically
descaled or acid cleaned, bare or
pre-coated, drawn with calcium and
sodium lubricants.
Applications include wire cleaning
from solid lubricant residue, or other
contaminants (rust and scale), prior to
galvanising, metallic coatings, Al or Cu
cladding, heat treatment, etc, and wire
rod cleaning prior to drawing.
The development of BH-S wire
dry cleaning system provides the
combination of simplicity and effective-
ness, replacing the most costly
operations in the wire cleaning process,
including replacement of acid, ultrasonic
and other wet chemicals, generating
substantial cost savings, environmental
benefits and improvement in productivity
of clean H/C and L/C wires.
The BH-S 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.
Basically, the BH-S is a smooth and
sensitive multi-layer micro-shaving/
abrading that finely impacts wire surface
separating lubricant residue or other
contaminants from the base material,
evacuating away dispersed contaminants
by moving wire, exiting the unit extra
clean of white-metal appearance at
extreme speed, and operating at virtually
zero energy consumption.
