High Power Graphite Electrodes is made of petroleum coke, needle coke, coal pitch and produced by a series of strict production processes. So let DanCarbon talk about high power graphite electrodes sales and uses.
1.What are High Power Graphite Electrodes?
High Power(HP) Graphite Electrode is mainly used for high power electric arc furnaces with the current density range of 18–25 A/cm2. 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.

3.High Power Graphite Electrodes Uses
Preparation of Jointing
(1) When raising the electrode from horizontal to vertical position, leave the pin protection in place or alternatively place a cushioning material underneath the pin to prevent damage to the threads.
(2) Clean the socket and end faces of the old column as well as of the new electrode with compressed air.
(3) In the case where some dirt should be removed manually, use a soft brush against the threads. Use of a metallic brush should be avoided.
