The graphite electrode for Electric Arc Furnace (EAF) is one of the key components in the metal melting process, especially in steelmaking. These electrodes are used to transfer high electric current and create an arc inside the furnace due to their high conductivity, resistance to extreme heat, and adequate mechanical strength.
Why Are Graphite Electrodes Essential for EAF?
In EAFs, graphite electrodes serve as the conduit for delivering electrical energy to the charged materials. The arc formed at the tip of the electrode generates intense heat, rapidly melting the metal.
Types of Electrodes Suitable for EAF
RP (Regular Power): Suitable for low-consumption furnaces with low current
HP (High Power): Ideal for medium consumption furnaces
UHP (Ultra High Power): Best suited for heavy-duty, high-current modern furnaces
