The new version of acid-free rod Dry
Cleaning, Coating and Drawing (DCCD)
process is rapidly changing the current
state of rod preparation and wire
drawing, replacing conventional rod wet
preparation, including acid cleaning/
rinsing/wet pre-coating and drying,
by the new totally dry and completely
"green" technology.
The DCCD process offers substantial cost
savings in the most demanding drawing
applications from mechanically descaled
uncoated rod, drawn directly without wet
pre-coating chemicals, including spring
wire, PC strand wire, cold heading wire,
plating wire, etc.
The process operates at ‘zero’ maintenance
cost as there is no acid, no hot liquid tanks
for rod pre-coating, no hot air blowers to
dry wet rod, and it operates at virtually
‘zero’energy consumption.
An added benefit is the automatic control
of lubrication parameters, including
lubricant pressure, temperature and
viscosity, enabling the use of standard
high melting lubricants (melting at
+220°C/428°F for H/C applications) which
are converted from solid into liquefied
state and instantaneously deposited on
uncoated rod to form a high-performance
lubricant film resisting at high load and
temperature, generating exceptional
thermal stability in all drafts at the
highest drawing speed, eliminating the
need for phosphate, borax and their wet
substitutes.
In operation, all lubrication parameters
‘communicate’ together in a sensitive
and automatic multi-way interaction
to form a hard and strongly adherent
full-film anti-wear lubricant coat,
weight-adjustable, enabling frictionless
drawing by physical separation of
wire-die contact in all drafts, eliminating
friction heat, providing superior surface
quality, increasing die life and improving
wire ductility.
Typical applications with DCCD processed
rod: Output of 2.2 tonne/hour with
5.5mm 0.83/0.88%C rod.
Spring wire is drawn at 18m/s (3,600ft/
min); 5.5mm 0.72%C rod drawn to
2.35mm at 16m/s (3,200ft/min); 10.5mm
0.85/0.88%C rod drawn to 4.22mm at
8-9m/s (1,800 ft/min).
