Wire lubrication control eliminates pre-coating chemicals Advertorial on behalf of Decalub

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. Decalub – France Fax : +33 1 60 20 20 21 Email : info@decalub.com Website : www.decalub.com

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
