The Dry Cleaning, Coating and Drawing
(DCCD) process offers substantial cost
savings replacing conventional rod wet
preparation (acid, phosphate, etc) by the
new totally dry, clean and green process
that presents a unique combination of
simplicity and effectiveness.
The DCCD process is used in-line in
the most demanding H/C and
L/C drawing applications from
mechanically descaled uncoated
bare rod, including 0.88-0.90%C,
drawn directly without wet
pre-coating chemicals, including
spring wire, rope wire, PC strand
wire, CO2 welding wire, cold heading
wire, plating wire, Al clad 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. The
rod moisture, the number one enemy for
wire drawing, is completely eliminated.
In operation, all lubrication variables
communicate together in a sensitive
and automatic multi-way interaction to
form a high-density, strongly adherent
full-film anti-wear lubricant carrier coat,
weight-adjustable, enabling frictionless
drawing benefiting from physical
separation of wire-die contact in all drafts.
This achieves a drawing speed of 18m/s
(3,600ft/min), output of 2.2-4.9 tonne/
hour for a rod diameter range of 5.5-13
mm (high carbon 0.73-0.88%C) and the
process operation cost at virtually triple zero
in terms of energy consumption,
lubricant waste andmaintenance.
The DCCD process revolutionises
the wire drawing process.
Customers target immediate
total savings of 50-64 per cent in
production cost of drawn wire, in all
drawing applications at virtually no
speed limit, dictated mainly by rod
pay-off and wire take up modes.
