Key Specifications of UHP 450mm & 600mm Graphite Electrodes

1. Physical and Technical Properties

• Diameter & Length:

  • UHP 450mm × 1800mm: Ideal for medium-capacity EAFs and submerged-arc furnaces.

  • UHP 600mm × 2400mm: Suited for high-capacity steel mills and large-scale metallurgical operations.

• Resistivity:

  • Electrode: 4.5–5.8 μΩ·m (ensures high conductivity).

  • Nipple: 1.80–1.85 μΩ·m (minimizes energy loss).

• Mechanical Strength:

  • Flexural Strength: ≥11 MPa (electrode), ≥20 MPa (nipple) for enhanced durability.

  • Elastic Modulus: ≤14 GPa (electrode), ≤18 GPa (nipple) to withstand thermal stress.

2. Material Composition & Quality Standards

• Raw Materials: Premium needle coke and petroleum coke (sulfur content <0.5%) ensure high thermal stability.

• Density: 1.66–1.75 g/cm³ (electrode), 3.0–4.3 g/cm³ (nipple) for optimal performance.

• Certifications: ISO 9001-compliant production, with ash content ≤0.3% for minimal impurities.

Industrial Applications

1. Steelmaking (EAF & LF Furnaces)

• EAF Steel Production: UHP electrodes enable faster melting, lower power consumption (~58% faster than copper electrodes), and reduced electrode consumption.

• Ladle Furnaces (LF): Used for secondary refining, improving steel quality with consistent arc stability.

2. Non-Ferrous Metallurgy

• Silicon & Ferroalloy Production: Essential in submerged-arc furnaces for smelting industrial silicon, ferrochrome, and titanium slag.

• Calcium Carbide & Phosphorus: High thermal efficiency reduces energy costs in chemical processing.

3. Specialty Applications

• Brown Fused Alumina & Titanium Slag: UHP 600mm electrodes handle extreme temperatures (up to 3,000°C) in refractory material production.

Why Choose Rongsheng’s UHP Electrodes?

1. Cost & Energy Efficiency

• Lower Power Consumption: Saves 30–50% energy compared to traditional electrodes.

• Reduced Labor Costs: Fewer electrode changes due to longer lifespan (up to 2–3x copper electrodes).

2. Supply Chain Reliability

• Global Exports: Proven track record supplying Severstal, Mechel, and Balakovo in Russia.

• Custom Packaging: Wooden crates ensure safe transit for UHP 600mm electrodes.

3. Future-Ready Solutions

• Oxidation-Resistant Coatings: Extend electrode life in high-oxygen environments.

• Custom Sizes & Threads (4TPI/3TPI): Tailored for specific furnace designs.

Market Outlook & Procurement Tips

• Pricing Trends: UHP 450mm electrodes average $1,600–$2,050/ton, while 600mm variants command $2,000–$2,800/ton.

• Buyer Recommendations:

  • Verify needle coke sourcing (critical for quality).

  • Prioritize suppliers with ISO 9001 certification (e.g., Rongsheng Graphite).
