How Much Does Graphite Electrode Cost?
How to choose Graphite Electrode?
Graphite Electrode is an indispensable material used in the electric arc furnace steel making, for its excellent electrical conductivity and remarkable anti-thermal shock capability.
How much does Graphite Electrode cost? How to choose the right Graphite Electrode?
The correct type of Graphite Electrode for varying operating conditions is mainly influenced by the maximum current carrying capacity.
The following table shows the different electrode types and their matching current carrying capacities and will provide a rough idea

The Grade of Graphite Electrode are mainly divided into: UHP - ULTRA HIGH POWER, HP - HIGH POWER, RP - REGULAR POWER.
Type HP:
High power grade Graphite Electrode is for foundry operations for ladel furnaces (LF) and occasionally for electric Arc Furnace (EAF) operations, if the furnace parameters are suitable.
Type UHP:
Untra high power grade Graphite Electrode is suitable for electric arc furnace (EAF) operations and ladle furnace (LF) operations with heavy current loads.
Maximum Current Load for EAF
Graphite Electrode Diameter/mm
Maximum Current Load for LF
Graphite Electrode Diameter/mm
Therefore, the customers should consider the above factors according to their own work requirements and select the appropriate Graphite Electrode.
