1. Project Background & Requirements

The Armenian client, METAL WORLD LLC, required an efficient reduction solution for φ8.0mm copper rods, with a focus on superior electrical properties and surface finish. Key requirements included:

• Inlet Diameter: φ8.0mm copper rod.

• Outlet Range: 1.38mm - 3.2mm.

• Product Quality: Final diameter tolerance within ±0.03mm, with a smooth, round surface free of defects.

• Energy Efficiency: Target power consumption around 160 KWH/hour.

2. Technical Support & Parameterized Evidence

The unit integrates the following technologies to ensure drawing stability and consistent physical properties:

• High-Efficiency Drawing: Features a 13-die process with φ560mm capstans. A consistent mechanical speed ratio of 1.25 and a maximum speed of 750 m/min ensure stable metal flow under high reduction ratios.

• Intelligent Annealing Control: Equipped with a WDL-350T continuous annealer (Max DC 4000A). The system features automatic voltage tracking, where the annealing voltage (up to DC 60V) adjusts according to line speed to maintain uniform elongation.

• Wear-Resistant Components: The drawing capstans are made of cast steel coated with Tungsten Carbide, significantly enhancing hardness and service life under high-speed friction.

• Low-Noise Drive: Powered by a 132KW AC main motor, maintaining mechanical noise levels at ≤80dB.

3. Equipment Composition & Specifications

The fully automated line includes:

• Core Units: 560/13D main drawing machine, WDL-350T continuous annealer, and a dual-spool take-up (11KW*2).

• Auxiliary Systems: A 2000L centrifugal filter ensures the purity of drawing oil, protecting both dies and wire surface.

• Premium Components: Major electrical switches and bearings are sourced from top-tier brands; total installed capacity is 250KVA.
