New Lubricant Viscosity Control (LVC)
system, used in conjunction with the
PDH ultra high-pressure lubrication
technology, can be used in the most
demanding drawing applications,
allowing mechanically descaled high- or
low-carbon rod to be drawn directly
at high speed, without pre-coating
chemicals.
LVC/PDH rod dry coating/lubrication
system uses three-way interaction
between the pressure, temperature
and lubricant viscosity to produce
a fusion of standard lubrication
compounds, liquefied to a viscosity
to suit the application. This eliminates
traditional pre-coating chemicals,
including phosphate and borax
pre-coating, and provides a consistent
residual coat in the first draft.
The system permits frictionless
drawing in remaining drafts with
the full lubricant film at wire-die
interface, giving physical separation
of metal-to-metal contact, in the most
demanding multi-draft applications from
rod to wire in a one-step operation.
The new rod dry coating/lubrication
system allows a wide range of residual
coats, from strongly adherent – for
high-tensile wire – to a light, water soluble
coat for plating wire.
Typical applications of the LVC/PDH dry
coating system include direct drawing
from mechanically descaled H/C rod,
without pre-coating chemicals, from
5.5mm down to 1.3mm at 18m/s, and to
3.25mm at 8.3m/s, with die life enabling
production of 200-220 tonnes/die in the
first draft.
The finishing die produces 40 to 60
tonnes of wire drawn without pre-coating
chemicals and with improved ductility,
cast and torsion.
LVC/PDH lubrication system features zero
energy consumption, self-generating
processing heat and pressure.
