| Decalub, France, has introduced a new high-performance steel rod/wire coating and lubrication system operating with �zero consumables cost� and with �zero energy consumption�, at unlimited rod entry speed. The new PDH lubrication system is used in the most demanding drawing applications, reducing die wear and enabling the highest drawing speeds with all carbon steel rods and wires, as well as stainless steel alloys. The PDH lubrication system offers immediate substantial cost savings in production of quality wires, including springs, ropes, bead, PC-strands, stainless steel spring and alloys, galvanised H/C wires, AL-cladded wires, plating wires, CO2 welding wires, colleted nail wires, etc. All those products are drawn from mechanically descaled rod or acid cleaned rod, bare or pre-coated, bright or galvanised.
The process features the innovative PDH rod/wire dry-coating and lubrication technology that enables an automatically controlled fusion of lubrication compounds, making them liquefied. Such a substance eliminates traditional pre-coating chemicals and achieves an exceptionally adherent and consistent residual coat, adjustable in weight, at all speeds. The wire coating / re-coating and lubrication technology achieves:
- Hard residual coat for spring wires, high-tensile rope wires, PC strand wires, etc;
- Light films, water soluble for plating wires.
The PDH wire lubrication process also enables die-life of 200 to 220 tonnes per die in the first draft, with 0.83 - 0.85%C 5.5mm � mechanically descaled bare rods drawn directly without pre-coating, and 60 to 80 tonnes per die in the finishing draft, with an output of 2.2 tonnes per hour. One of the system�s new applications in production of clean wire include high-carbon green rods that are mechanically descaled and directly drawn, without pre-coating, with Na-based lubricants in all drafts, enabling in-line wire cleaning for wire plating, galvanising, brass coating, etc. Fully automatic, the system is easy to operate and simple to install on any wire dry drawing machine.
