Production Process for Cold Drawn Wire

Surface Treatment

Select high-quality carbon wire rod. Then, use a multi-roller machine to peel off surface slag, followed by acid pickling to dissolve residual oxide layers. After rinsing with clean water until no acid residue remains, dry the rod and finally lubricate it.

Core Drawing

Install drawing dies made of materials such as cemented carbide, ensuring the dies are concentric with the drawing axis. Then, use a cold drawing machine clamp to hold the pre-treated material and pull it through the die hole. The machine’s pulling force causes the material to undergo plastic deformation at room temperature.

Multiple Drawings

To achieve target specifications, multiple drawing processes are often performed. Intermediate annealing is incorporated into the drawing process, using a short online heat treatment to eliminate some internal stress and restore plasticity for subsequent processing.

Post-Processing

First, use a multi-roller straightener to correct any bends in the drawn wire, ensuring it meets straightness requirements. Then, perform targeted surface treatments depending on the application, such as annealing, galvanizing for corrosion protection, or straightening and cutting for finishing.

Cold Drawn Wire Applications

• In industry, it is used to manufacture automotive steering shafts, gears, springs, bolts, and other components. It can also be used as a raw material for wires and connectors in the electronics and electrical industries.
• In agriculture, it can be used to build greenhouse frames, livestock cages, and to make protective netting and fences for crops, resisting external impacts and resisting deformation.
• As a core building material, cold-drawn wire is used for reinforcing concrete components, as prestressed steel bars, and as wall tie bars. It can also be used to make wire mesh to prevent plaster cracking.

• In large-scale engineering projects, cold-drawn wire can be processed into steel cables and anchor rods, suitable for high-strength load-bearing scenarios such as bridge suspension cables and foundation reinforcement.
• In everyday life, it can be used to DIY clothes hangers, hooks, and small tools. It can also be used to make security windows and guardrails. Some specifications can also be used for louvered light-adjusting rods and paper clips.
• In horticulture, it can be used to make fences and ties for flower stands. Thinner specifications are suitable for twining vines, while medium-sized specifications can be used to secure flower stands.
