Product Description

Product Description

Graphite Electrode | High-Performance Electrode for Electric Arc Furnace (EAF) Steelmaking

Graphite Electrodes are critical conductive components in electric arc furnaces (EAF) and ladle furnaces, enabling efficient conversion of electrical energy into extreme heat (1500-3500°C) for steel production, non-ferrous metal smelting, and alloy refining. As a leading graphite electrode manufacturer, we deliver premium-grade electrodes tailored for industrial metallurgy, foundries, and recycling plants worldwide.

Applications of Graphite Electrodes
Graphite Electrodes are indispensable in modern metallurgical processes:

Steel Industry: Primary melting of carbon steel, stainless steel, and electrical steel in EAFs.
Non-Ferrous Metals: Smelting copper, silicon metal, and titanium alloys for automotive and electronics sectors.
Specialized Refining: Production of ferroalloys, industrial silicon, and yellow phosphorus in submerged arc furnaces.
Recycling: Scrap metal recycling for green steel production with reduced carbon footprint.

Key Product Features & Specifications

2. Choose by Smelted Metal Type

Basic Metals (Carbon Steel/Cast Iron)

1. Core Needs: Cost Priority, Stable Melting Efficiency, Medium-Load Tolerance.

2. Recommend RP Electrode:

    -Ash ≤0.5% prevents impurity contamination, meeting basic metal purity standards;
    -Bending strength ≥8.5MPa withstands regular temperature fluctuations, reducing breakage risks;

    -12% lower cost than similar products, ideal for bulk procurement to control budgets.

Alloy Steel/Ferroalloy/Special Steel

1. Core Needs: High conductivity for energy savings, long life for continuous operation, low sulfur/phosphorus for metal quality.

2. Recommend HP Electrode:

    -Resistivity 4.5-6.5μΩ·m, 30% higher conductivity than RP, cutting power consumption by 15% per ton;

    -Pitch-impregnated coating reduces high-temperature loss by 15%, extending life by 20% for 24/7 high-load smelting;

    -Full diameter range adapts to 50-150 ton furnaces with varying charge sizes.

Stainless Steel/Electrical Steel/Nickel-Based Alloys/New Energy Materials

1. Core Needs: Ultra-high conductivity for speed, extreme anti-loss for minimal downtime, ultra-purity for premium standards.

2. Recommend UHP Electrode:

    -Resistivity ≤5.5μΩ·m + 800mm large diameter shortens smelting time by 25%, boosting daily output by 30%;

    -Dual-coating (SiC CVD + Pitch Impregnation) limits oxidation to 0.15mm/h, extending life by 25% over HP and cutting annual loss costs by 40%;

    -Ultra-purity (ash ≤0.2%) certified to IATF 16949, ideal for critical applications such as lithium battery anode graphitization.

3. Choose by Production Scale & Cost Goals

Small-Medium Enterprises/Intermittent Production:
Prioritize RP Electrode for lower initial investment (30% cheaper than HP), standardized sizes for quick installation, and reduced equipment debugging costs.

 

Large-Scale Steel Plants/Continuous Production:
Opt for HP Electrode to leverage conductivity and longevity in high-load operations. Long-term electricity savings (over 20% monthly) far outweigh initial cost differences, offering superior total cost efficiency.

 

High-End Smelting/New Energy Industries:
Select UHP Electrode despite higher upfront costs (3-4x RP). Its efficiency gains (25% faster smelting) and quality assurance (high-purity certification) help break into high-margin markets, delivering 10%-15% lower total cost per ton in premium applications.

4. . Choose by Industry-Specific Requirements

Submerged Arc Furnace Smelting (Industrial Silicon, Yellow Phosphorus):

· Recommend RP/HP Electrode based on furnace size:

· Small furnaces (≤5000kVA): RP for cost control;

· Large furnaces (≥10000kVA): HP for long-term high-temperature load resistance and reduced electrode consumption.

 

New Energy Material Production (Lithium Battery Anodes, Photovoltaic Silicon):

· UHP Electrode is a Must due to:

  -Ash ≤0.2% to avoid metal ion contamination, critical for lithium battery-grade graphite;

  -Ultra-high conductivity speeds up graphitization, shortening batch processing time by 20% to meet explosive new energy demand.

Export-Oriented Enterprises (EU/US Compliance):

· Recommend HP/UHP Electrode with additional focus on:

  -CE certification (both HP/UHP) and REACH registration (UHP pre-registered);

  -UHP's low-carbon process (optional low-temperature graphitization) to meet EU CBAM carbon tariff requirements for high-power products.
