661±2 UHP Graphite Electrode , 2400mm, 2700mm
 
 
Sichuan Guanghan Shida Carbon Co., Ltd. ,established in 1990, is a high-tech company, professional production of graphite electrode 30 years. The range of graphite electrode is 450-700mm diameter with RP,HP,UHP grade. Especially UHP600,UHP650 and UHP700 are our main sales products.
 
Graphite electrode is widely used in electric arc furnace (EAF), ladle furnace(LF) for steel making and submerged arc furnace (SAF). The good performance and low consumption of graphite electrodes can reduce users' large cost. 

Specific Electrical Resistance (SER or ER): low specific resistance of graphite electrodes allows maximum current carrying capability without overheating of the electrode column.

Bulk density: a higher bulk density will generally be reflected in improved mechanical properties

Flexural strength, higher flexural strength in electrodes will generally result in lower

electrode breakage frequency.

Coefficient of Thermal Expansion (CTE): lower CTE will generally give better resistance to thermal shock. Also, CTE compatibility between the graphite electrode and connecting nipple is important for satisfactory performance of the electrode joint.
