Product Description

RP HP UHP 200mm Graphite Electrode EAF Carbon Graphite Electrodes for Ladle Furnace

 

Description:

Graphite Electrode
The graphite electrode will be a high-temperature graphite conductive material, the core of which consists of petroleum coke, tar coke as a filler, coal tar as a binder. We produce graphite electrodes,nipples and blocks to them. Graphite electrodes are characterized by low resistance, good electrical conductivity and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc.

Applications of Graphite Electrode UHP

1.For arc furnaces of electric arc furnaces. Graphite electrodes are most often used in a coal-smelting electric furnace. 2.For a closed arc 3.For a resistor furnace 4.For the production of graphite shaped products. The graphite electrode blank is also used for processing in various crucibles,shapes, boats and heating elements and other graphite products. For example, in the quartz glass industry, for each production of 1 ton of an electric melting tube, a graphite electrode 10 m is required, for each quartz brick of 1 ton it is necessary to consume 100 kg of graphite electrode.

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.

Production Application:

  1. Core application in Electric Arc Furnace (EAF) steelmaking (accounting for over 70% of global consumption): Conduct electricity to generate high-temperature electric arcs for melting scrap steel, producing construction steel, automotive steel and specialty steel
  2. Facilitate non-ferrous metal smelting: Smelt metals such as copper, nickel and lead; also used in vacuum remelting of refractory metals like titanium to achieve purification and uniform composition
  3. Produce key industrial materials: Manufacture metallurgical-grade silicon, polysilicon (for solar energy/semiconductors), as well as phosphorus and ferroalloys in submerged arc furnaces
  4. Serve the electrochemical industry: Act as anodes in electrolytic refining of metals like copper and gold for purification, or as current collectors in fuel cells to ensure stable electricity transmission
  5. Support specialized industries: Assist in high-temperature production of glass/ceramics (reducing energy consumption); also used in laboratory high-temperature experiments and electrochemical analysis
