Lubrication provides rod anti-friction coat at all speeds

Advertorial on behalf of Decalub

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, CO 2 welding wire, plating wire, cold heading wire, etc. 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. The LVC/PDH lubrication system features automatic control of lubrication parameters, Eraser’s model RT2S fine magnet wire stripper will strip film type insulations including Formvar, ML, enamel, varnish, isonel, and more from 28AWG to 48AWG. The conical wheels rotate at high speed to generate frictional heat which softens the insulation on the wire. The machine features a strip length stop for consistent strip lengths, a dust take-off port for environmental safety and close-up, multiple-wire stripping capability. The unit also cleans and polishes leads of small electronic components and removes oxidation and other contaminants from leads as small as 0.0012" diameter.

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).
