Product Description

Supply High Quality Graphite Electrode For Electric Arc Furnace Steelmaking​

 

Description:

Graphite electrode is a conductive carbon rod, primarily used in Ultra High Power (UHP) Electric Arc Furnaces (EAFs), to generate intense heat (over 3,500°C) that melts scrap steel for recycling, leveraging graphite's unique properties like high thermal conductivity, electrical conductivity, and strength at extreme temperatures. These large cylindrical electrodes, made from needle coke, form an electric arc with the metal, enabling efficient, resource-saving steel production.
How They Work in Steelmaking
Current Delivery: Massive electrical current is sent through the graphite electrodes.
Arc Formation: An electric arc forms between the electrode tips and the steel scrap.
Melting: The arc's intense heat melts the scrap into new steel.
Assembly: Electrodes are connected into columns using threaded nipples for continuous operation.
Applications Beyond Steelmaking
Electrochemical Cells: Used as counter electrodes in corrosion testing and other lab applications due to chemical stability.
EDM (Electrical Discharge Machining): Used as tools for shaping metal.
Grades
UHP (Ultra High Power): For modern, high-productivity furnaces, made from premium needle coke.
HP (High Power) & RP (Regular Power): Other grades for different furnace demands.

Applications of Graphite Electrode UHP

Graphite electrode uhp can be widely used in electric arc furnace and ladle refining furnace for steelmaking. uhp graphite electrodes can be widely used in the electric smelting furnace for producing the ferroalloy, pure silicon, yellow phosphorus, copper matte, calcium carbide and so on.


Characteristics Of Graphite electrodes: 

1. Excellent Thermal Conductivity Graphite boasts exceptional thermal conductivity, far superior to most metals. It can efficiently transfer heat and maintain stable thermal performance even in extreme temperature environments (from ultra-low to high temperatures above 3000℃). This advantage makes it an ideal material for heat dissipation components, high-temperature furnaces, and thermal management systems in electronics, metallurgy, and aerospace industries.

 
2. High Temperature Resistance With an extremely high melting point (around 3652℃) and boiling point (4827℃), graphite can maintain its structural integrity and mechanical properties without melting or decomposing under high-temperature conditions. It is resistant to thermal shock and can withstand rapid temperature changes, which is crucial for applications in high-temperature smelting, aerospace engine parts, and high-temperature experimental equipment.
 
3. Good Electrical Conductivity As a good electrical conductor, graphite has low electrical resistivity and excellent current-carrying capacity. It is widely used in the production of electrodes, brushes, conductive plates, and other electrical components.
 
4. Outstanding Chemical Stability Graphite is chemically inert and not easy to react with most acids, alkalis, and organic solvents.
 
5. Excellent Lubrication Performance Graphite has a layered crystal structure, and the layers can slide easily, providing excellent self-lubricating performance. It can work stably without additional lubricants, even under high load, high temperature, and high speed. This advantage makes it an ideal lubricating material for mechanical parts, molds, and sliding components, reducing friction and wear and improving equipment operation efficiency.
 
6. Light Weight and High Strength Compared with traditional metal materials, graphite products are lighter in weight while maintaining high mechanical strength and hardness.
