Smelting Steel Eaf Graphite Electrodes / Carbon Graphite Electrode 450mm Diameter
450UHP Graphite Electrode for EAF or LF , UHP450 for Smelting Steel
Shida Carbon is Chinese leading plant of manufacturing graphite electrode and istropic graphite, established in 1990. As Chinese top4 brand of graphite electrode, Shida carbon owns the full production facilities from raw material to graphitization and machining which can fully guarantee the stable quality.
Good graphite electrode performance:
Resistance: low resistance of graphite electrode 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.
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.
