Product Description

Self-Baking Electrodes & Electrode Paste

Overview

As critical conductive components for submerged arc furnaces (SAFs) in ferroalloy, silicon metal, and phosphorus production, our self-baking electrodes and electrode paste deliver stable performance, cost efficiency, and adaptability to high-temperature industrial processes.

1. Self-Baking Electrodes

Designed for on-site sintering, these electrodes eliminate pre-baking procedures, reducing logistics costs and ensuring seamless compatibility with SAF operations.

• Key Advantages:
  • On-site formation adapts to furnace size (no fixed length limitation).
  • High thermal shock resistance (withstands 1,800-2,200°C furnace temperatures).
  • Low electrical resistivity (≤85 μΩ·m) ensures efficient current transmission, cutting energy consumption by 3-5%.
  • Dense structure minimizes oxidation loss, extending service life by 15-20% vs. standard electrodes.

2. Electrode Paste (Raw Material for Self-Baking Electrodes)

A homogeneous mixture of calcined petroleum coke, coal tar pitch, and additives, our electrode paste enables smooth sintering and reliable electrode performance.

• Key Advantages:
  • Controlled softening point (75-95°C) ensures easy molding without cracking.
  • Low ash content (<0.5%) prevents impurity introduction into molten metals (critical for high-purity silicon/ferroalloys).
  • Excellent coking value (>82%) guarantees strong mechanical strength after sintering.
