Wire friction, wear and lubrication

Wire lubrication by GP/PDH system
Wire lubrication by GP/PDH system

The PDH lubrication system is used in the most demanding drawing applications, allowing the highest drawing speeds, with all carbon steel rods/wires, mechanically descaled or acid cleaned, bare or pre-coated, bright or galvanized, including spring, high-tensile rope, PC strand, stainless steel spring, galvanised H/C and L/C wire, plating wire and CO2 welding wire.

The PDH system uses a unique multi-way interaction of lubricant pressure, temperature and viscosity to convert a solid lubricant into a liquefied solution and maintain its thermal stability at all drawing speeds, eliminating conventional wet pre-coatings for all drawing applications form rod, including mechanically descaled 0.90%C rod drawn without pre-coating chemicals.

The system is highly regarded for its unique ability to provide closed circuit pressure lubrication at 350 bars, controlled lubricant injection at wire speed of 22 m/s and lubricant thermal stability at 240°C. The PDH system performs a high-performance wire rod dry coating with completely fused lubricant deposited instantaneously, in 5 to 10 micro seconds, operating at zero energy consumption, performing a high-density strongly adherent hard anti-friction (anti-wear) multi-layer coat with adjustable coating weight up to 8–10g/m2, at will, completely eliminating the need for phosphate and borax wet pre-coating chemicals.

A typical application consists in drawing 5.5mm 0.83/0.88% C, mechanically descaled rod, without wet pre-coating, with an output of 2.2 tonne/hour and a die life of 200 tonnes/die in the first draft and 40 to 60 tonnes of wire drawn in last draft, with superior surface quality and improved wire ductility.
