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, CO 2 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.
