Generation of unavoidable fi nes (abrasive particles), the most destructive lubricant contaminants in wire drawing, is no longer an alarming phenomenon since the introduction of the Decalub green and dry rod preparation and wire lubrication, including PDH coating system.

In the most demanding wire applications, PDH die wear is reduced to an unmeasurable level (about 0.2 micron per tonne), meaning the three-body abrasive wear is virtually eliminated. Generated abrasive particles (fines), continuously liberated from the wire surface during drawing, are PDH captured, encapsulated and transported with drawn wire out of the machine.

The lubricant film created is of such a confi guration as to induce a hydrodynamic lubricant activity causing migration of all lubricant contaminants without interference with the die, meaning the removal of abrasive particles prevents die wear, enabling frictionless wire drawing at unlimited extreme speed and low temperature.

The PDH high-performance specific coat is hard, has a high density, and is adjustable in thickness, largely suffi cient to retain all liberated abrasive particles from the wire surface.

Applications include all plain carbon wires up to 0.98 per cent carbon, coated or uncoated, and stainless steel alloy wires up to 26 per cent chromium.
