Rod cleaning and wire drawing by DCCD process

The rod dry cleaning, coating and drawing (DCCD) process offers cost savings, replacing conventional rod wet preparation, including acid cleaning, rinsing, wet pre-coating chemicals and drying. The new rod preparation version is totally dry, green and clean and features a combination of simplicity and effectiveness.

The DCCD process is used in demanding H/C and L/C drawing applications from mechanically descaled bare rod, including 0.88-0.90%C, drawn directly without wet pre-coating chemicals, in applications including spring wire, PC strand wire, CO2 welding 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 and no hot air blowers to dry wet rod, and it operates at virtually zero energy consumption.

The rod moisture, a significant problem in wire drawing, is totally eliminated, meaning the rod can be drawn at virtually infinite die life.

In operation, all lubrication variables communicate together in a sensitive and automatic multi-way interaction, forming a high-density, strongly adherent, full-film anti-wear lubricant coat, weight-adjustable, that potentially captures and evacuates lubricant's most destructive abrasive contaminants (unavoidable metallic fines), enabling frictionless drawing with virtually no measurable die wear, and benefiting from physical separation of wire-die contact in all drafts.

Compact and easy to install, the DCCD process provides cost savings and efficiency in wire drawing with virtually no speed limit.
