Rod preparation: Drawing art of steel wire - clean, green and dry

Rod cleaning and wire drawing by DCCD process
Rod cleaning and wire drawing by DCCD process

The Dry Cleaning, Coating and Drawing (DCCD) process offers substantial cost savings replacing conventional rod wet preparation (acid, phosphate, etc) by the new totally dry, clean and green process that presents a unique combination of simplicity and effectiveness.

The DCCD process is used in-line in the most demanding H/C and L/C drawing applications from mechanically descaled uncoated bare rod, including 0.88-0.90%C, drawn directly without wet pre-coating chemicals, including spring wire, rope wire, PC strand wire, CO2 welding wire, cold heading wire, plating wire, Al clad 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. The rod moisture, the number one enemy for wire drawing, is completely eliminated. In operation, all lubrication variables communicate together in a sensitive and automatic multi-way interaction to form a high-density, strongly adherent full-film anti-wear lubricant carrier coat, weight-adjustable, enabling frictionless drawing benefiting from physical separation of wire-die contact in all drafts.

This achieves a drawing speed of 18m/s (3,600ft/min), output of 2.2-4.9 tonne/ hour for a rod diameter range of 5.5-13 mm (high carbon 0.73-0.88%C) and the process operation cost at virtually triple zero in terms of energy consumption, lubricant waste and maintenance.

The DCCD process revolutionises the wire drawing process. Customers target immediate total savings of 50-64 per cent in production cost of drawn wire, in all drawing applications at virtually no speed limit, dictated mainly by rod pay-off and wire take up modes.
