Rod phosphate-free conversion coating by PDH system

Today, replacement of conventional wire rod wet preparation by the PDH system phosphate-free conversion coating changes rapidly the current state of wire drawing, generating lower operating cost and benefitting from significant energy and maintenance savings, and complete environmentally friendly rod conversion coating and wire lubrication process.

Users have been attracted by the PDH coating technology, which is potentially less complex, much cheaper, simpler and more convenient to use.

The PDH system is used in-line in the most demanding drawing applications with all carbon steel rods and wires, including 0.90%C , mechanically descaled or acid cleaned, uncoated or pre-coated, in applications including spring wire, rope wire, PC strand wire, plating wire, cold heading wire, galvanised wire, CO2 welding wire, etc.

The PDH system achieves a unique scenario in modern wire drawing operations, making the process green, dry, clean, instantaneous, self-controlled, repeatable, in-line, and operating at virtually zero energy consumption.

The major positive impact is immediate:

  • Unlimited rod coating speed
  • Frictionless drawing
  • Output 2.2-4.9 tonnes per hour (from 5.5-13mm H/C uncoated rod)
  • Minimal die wear (0.1-0.3 micron per tonne)
  • Replacement of phosphate, borax and wet substitutes by a powder compound
  • Hard and consistent fully controlled anti-friction coat that captures abrasive particles eliminating two-body abrasion wear (the most destructive lubricant contaminant)
  • Elimination of moisture, which is the number one enemy in the wire drawing process (the second most destructive lubricant contaminant)
  • Extremely compact unit, easy to incorporate into existing operation
  • Providing very smooth wire finish not difficult to clean with water
