Rod dry preparation and direct drawing

lubricant deposited instantaneously on rod/wire surface, operating at zero energy consumption, performing a high-density strongly adherent anti-wear multi-layer coat with adjustable weight, completely eliminating the need for phosphate and borax wet pre-coating chemicals. The PDH lubrication system prevents metal-to-metal contact at wire-die interface, enabling frictionless drawing, providing superior surface quality and improved wire ductility.

Typical applications of the DCCD process are: output of 2.2 tonne/ hour with 5.5mm 0.83/0.88%C rod, in a ‘frictionless’ drawing application with die life of 200 tonnes/die in the first draft and a die wear of 0.1 to 0.3 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); 10.5mm 0.85/0.88%C rod drawn to 4.22mm at 9m/s (1,800ft/min).

ADVERTORIAL ON BEHALF OF DECALUB

The DCCD (Dry Cleaning, Coating and Drawing) process offers substantial cost savings in the most demanding drawing applications from mechanically descaled bare rod, drawn directly without wet pre-coating chemicals, including spring wire, PC strand wire, cold heading wire, plating wire, etc. The process operates at ‘zero’ maintenance cost as there is no acid, no hot liquid tanks for rod pre-coating, no hot air blowers to dry wet rod, and it operates at virtually zero energy consumption. An added benefit is the 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 deposited on bare rod in a few

microseconds, generating exceptional thermal stability at the highest drawing speed, eliminating phosphate, borax and their wet substitutes. In operation, all these parameters ‘communicate’ together in a sensitive and automatic multi-way interaction to form a hard and strongly adherent full-film anti-wear lubricant coat, weight-adjustable, enabling frictionless drawing by physical separation

Decalub’s pressure-die anti-wear lubrication

The PDH lubrication system is used in the most demanding drawing applications, allowing highest drawing speeds, with all carbon steel rods/wires, mechanically descaled or acid cleaned, bare or pre-coated, including spring wire, high-tensile rope wire, plating wire, cold heading wire, etc. The system is highly regarded for its unique ability to convert a solid lubricant into a liquefied solution and maintain its thermal stability (at 200 to 240°C) at all drawing speeds. a high-performance wire rod dry coating/ lubrication with completely fused The PDH system achieves
