Lubricant Viscosity Control Eliminates Pre-coating Chemicals

The new innovative Lubricant Viscosity Control (LVC) system, operating in conjunction with the PDH ultra highpressure lubrication technology, is used in the most demanding drawing applications, allowing mechanically descaled highcarbon, or low-carbon rod, to be drawn directly, without pre-coating chemicals, at the highest speeds.

The LVC/PDH rod dry coating/lubrication system benefits from the most unique fully controlled 3-way interaction between the pressure, temperature and lubricant viscosity, enabling an automatically controlled fusion of standard lubrication compounds, making them molten/liquefied with a viscosity suitable for the application. Such a substance eliminates completely traditional pre-coating chemicals and performs an exceptionally adherent and consistent residual coat in the 1st draft,operating in close circuit lubrication, automatically adjustable in weight at all speeds without limitation, completely eliminating traditional wet pre-coatings for all drawing applications, including mechanically descaled 0.90%C bare rod.

The system permits full film �frictionless� drawing in remaining drafts, benefiting from the innovative LVC/PDH rod dry coating/lubrication technology, completely eliminating the need for phosphate and borax pre-coating chemicals and their substitutes 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, strongly adherent for high-tensile wire, and 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 1.3-3.25mm at 18-8.3m/s, and with die life enabling production of 200-220 tons/die in the first draft.
