What is Graphite Electrode?

Artificial Graphite Electrode is an indispensable material used in the electric arc furnace steel making, for its excellent electrical conductivity and remarkable anti-thermal shock capability.

In general, carbon is produced by carbonizing mixed coke substances with binding pitch at 1,000°C in a baking furnace. When this carbon is graphitized in an electric furnace at 3,000°C, the amorphous carbon body takes on the structure of crystalline graphite. This is called graphite. Carbon materials are usually pitch impregnated and re-baked to enhance electrical and mechanical properties before graphitization.

Graphite has the features of---

High temperature strength

Good thermal and electrical conductivity

Low thermal expansion

Appropriate machinability

These features make Graphite Electrode the most suitable material to melt scraps, DRI, etc. by arc energy.
