Rod coating and lubrication by LVC/PDH system

The innovative LVC/PDH lubrication system provides a high-performance anti-friction coat, reliable lubrication for the most demanding drawing applications, allowing the highest drawing speed with all steel rods/ wires, including mechanically descaled uncoated 0.85-0.88 %C rod.

Applications include drawing of spring wire, high-tensile rope wire, PC strand wire, CO2 welding wire, plating wire, cold heading wire, etc.

The LVC/PDH lubrication system features 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 converted from solid into liquefied state and instantaneously deposited on bare rod, generating exceptional thermal stability in all drafts at the highest drawing speed, replacing phosphate, borax and their wet pre-coating substitutes, completely eliminating rod residual moisture.

In operation, all these parameters 'communicate' together in a sensitive and automatic multi-way interaction to form a consistent exceptionally adherent full-film anti-friction lubricant coat, weight-adjustable, enabling frictionless drawing by physical separation of wire-die contact in all drafts, eliminating friction heat, greatly increasing die life, providing superior surface quality and improved wire ductility.

Typical applications with the LVC/PDH coated rod: Output of 2.2 tonne/hour with 5.5mm 0.83-0.88%C mechanically descaled bare rod, in a 'frictionless' drawing application with die life of 200 tonnes/die in the first draft and a die wear of 0.20 micron/tonne of wire drawn in the last draft.

Spring wire is drawn from mechanically descaled bare rod, without pre-coating chemicals, at 18m/s (3,600ft/min); 5.5mm 0.72 %C rod drawn to 2.35mm at 16m/s (3,200ft/min); 0.5mm 0.85-0.88 %C rod drawn to 4.22mm at 8-9m/s (1,800ft/min).
