Graphite Electrode 100-750mm

Graphite electrodes (100–750 mm) are premium conductive tools engineered for high-temperature industrial processes, leveraging graphite's unique properties to deliver efficient, durable performance in EAFs, LFs, and other metallurgical reactors.

​​:

​​: 10–30% higher than standard carbon materials, reducing energy waste.

​​: Minimizes dimensional changes under heating/cooling, preventing cracks.

​​: Stable at 1,500–3,000℃, unlike metals (e.g., copper, which melts at 1,085℃).

​​Size-Driven Applications​​:

​​100–300 mm​​: Used in small-scale applications like laboratory furnaces, pilot EAFs, or LF auxiliary heating, where lower power (10–30 kA) and space constraints dominate.

​​300–500 mm​​: Standard for mid-sized EAFs (50–150 tons), supporting 30–80 kA and balancing cost with throughput.

​​500–750 mm​​: Critical for large EAFs (150–300 tons), where they handle 80–120 kA currents to melt 200+ tons of scrap per heat, optimizing tap-to-tap times.
