The Dry Cleaning, Coating and Drawing
(DCCD) process offers substantial cost
savings, replacing conventional rod wet
preparation including chemical cleaning/
rinsing/wet pre-coating and drying by
a new, totally dry process that presents
a unique combination of simplicity and
effectiveness.
The DCCD process is used in the most
demanding H/C and L/C drawing
applications from mechanically descaled
bare rod, including 0.88-0.90%C, 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 (+220°C/428°F)
which are instantaneously converted from
solid into liquefied state and deposited on
bare rod, generating exceptional thermal
stability at the highest drawing speed,
18m/sec for spring wire, completely
eliminating the need for phosphate and
borax pre-coating chemicals and their
wet substitutes.
In operation, all lubrication parameters
‘communicate’ together in a sensitive
and automatic multi-way interaction to
form a high-density strongly adherent
full-film anti-wear lubricant coat,
weight-adjustable, enabling frictionless
drawing by physical separation of
wire-die contact in all drafts.
The DCCD process revolutionises wire
drawing process: customers target
immediate total saving of 50-64% 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.
