Product Description

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke 

and widely used in the electric arc furnaces for production of alloy steels, metal and other 

nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 

700mm. Our products own the following characteristics: low electric resistance, good electric and 

thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

Do you know our material of the graphite electrode? 

 

The regular power graphite electrode is made from petroleum coke with a little pitch, which meets

 the state standards YB/T4088-2000

 

The high power graphite electrode is made form 70% petroleum coke and 30% imported needle 

coke, which meets the state standards YB/T4089-2000

 

The ultra high power graphite electrode is made form 100% imported needle coke, which meets 

the state standards YB/T 4090-200

 

Note: Needle coke is one kinds of very important material to produce the high grade graphite 

electrode,which is rapid development in carbon graphite industry. The needle coke own the 

following characteristics: low electric resistance, low dilatation coefficient, good electric and 

thermal conductivity,high oxidation resistance, greater resistance to thermal and mechanical 

shock, high mechanical strength, high machining accuracy, low consume.
