Frequently Asked Questions (FAQ)
Q1: What is a Regular Power Graphite Electrode?
Regular Power Graphite Electrodes are standard-grade graphite electrodes used primarily in electric arc furnaces for steelmaking. They offer good conductivity and are suitable for general melting processes.
Q2: What are the typical specifications of Regular Power Graphite Electrodes?
They usually have moderate electrical conductivity, density, and mechanical strength. Standard diameters range from 150mm to 700mm, with lengths typically between 1200mm to 2700mm, depending on customer requirements.
Q3. What are the main applications of Regular Power Graphite Electrodes?
These electrodes are commonly used in electric arc furnaces (EAF) and ladle furnaces (LF) for steel production, foundry operations, and other metallurgical processes requiring electric resistance heating.
Q4: How is Regular Power Graphite Electrode different from High Power or Ultra High Power Electrodes?
Regular Power electrodes have lower electrical conductivity and mechanical strength compared to High Power (HP) and Ultra High Power (UHP) electrodes. HP and UHP are designed for more demanding, higher current applications and offer longer service life and better performance under intense operating conditions.
Q5: What materials are used to manufacture Regular Power Graphite Electrodes?
They are made from high-quality petroleum coke and coal tar pitch, which are calcined, shaped, baked, and then graphitized to form the final electrode.
