HP GRAPHITE ELECTRODES – the Diameters Range From 200 mm to 600 mm

HP graphite electrode is mainly used for high power electric arc furnaces with the current density range of 18–25 A/cm2.

Description：

HP graphite electrode is the conducting element for electric arc furnaces steelmaking. It is made of petroleum coke, needle coke, coal pitch and produced by a series of strict production processes. High-current lines insert through the graphite electrode port inside the furnace body. This will releases electric energy in the arc furnace to heat the furnace.

The demand for the larger diameter electrodes has been increasing as EAF furnace sizes become larger. Graphite electrodes with diameter of 500 mm or 600 mm have become increasingly popular in recent years.

Features：

Anti-oxidation treatment for longevity;
High-purity, high-density, strong chemical stability;
High machining accuracy, good surface finishing;
High mechanical strength, low electrical resistance;
Resistant to cracking & spalling;
High resistance to oxidation and thermal shock.

Applications：

Graphite electrodes are widely used for production of alloy steels, metal and other nonmetallic materials, etc.

DC electric arc furnace.

AC electric arc furnace.

Submerged arc furnace.
