Graphite Electrode

In the steelmaking process, iron scrap gets melted in an electric arc furnace and recycled. Graphite electrodes, a kind of conductor, are an essential component in this kind of furnace. They can melt scrap at a temperature of about 1600℃.

BSFC

Essential Conductor for Modern Steelmaking
In high-efficiency electric arc furnaces (EAF) and ladle furnaces (LF), graphite electrodes are the critical conductors that enable melting and refining of steel scrap at temperatures exceeding 1600°C. With exceptional thermal conductivity, low electrical resistance, and superior heat & impact resistance, they ensure stable furnace operation under the most demanding production conditions.

Applications

  • Electric Arc Furnace (AC & DC) – Used for melting recycled steel scrap at temperatures of around 1600°C.

  • Ladle Furnace (LF) – For secondary refining of molten steel, allowing alloy adjustment and removal of inclusions.

  • Foundries – Precision melting of specialty alloys and casting-grade steel.

  • Special Alloy Production – Ideal for producing high-performance alloys containing nickel, chromium, molybdenum, and other elements.

  • Metallurgical R&D Facilities – Utilized in research environments for highly controlled melting processes.

Advantages

  • High Current-Carrying Capacity – Capable of safely handling large electric currents in both AC and DC furnaces.

  • Low Unit Consumption Rate – Lower electrode consumption per ton of steel, reducing operational costs.

  • Superior Thermal Shock Resistance – Withstands rapid temperature changes with minimal risk of cracking or breakage.

  • Optimized Electrical Conductivity – Low electrical resistance minimizes energy loss during operation.

  • Dimensional Stability – Maintains size and structural integrity even after prolonged use.

  • Multiple Size Availability – Available in diameters from 14” to 32” for AC, DC, and LF furnaces.

  • Extended Service Life – Manufactured with advanced materials and processes for longer operational life.

  • Consistent Arc Stability – Ensures uniform heat distribution with stable arc performance.

  • Low Ash Content (<0.2%) – Minimizes contamination of molten metal.

  • Global Standards Compliance – Produced in accordance with ISO, ASTM, and other international standards.
