Product Description

Ultra High Power 700mm Graphite Electrode for Eaf Furnace Steel Smelting​

 

Description:

Graphite electrodes are used mainly in ladle furnaces, electric-arc furnace steelmaking, Yellow phosphorus furnace, Industrial silicon furnace, or melting copper. They are presently the only products available that have high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. High-Quality Needle Coke in HP&UHP graphite electrode, ensures the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
 

Explore the diverse grades available within our electrode portfolio, including:

· HP - High Power

· HD - High Density

· UHP - Ultra High Power

· SHP - Super High Power

Graphite electrodes are indispensable in electric arc furnaces (EAF), offering unmatched electrical conductivity and resilience against the intense heat levels inherent in these processes. They are also crucial for refining steel in ladle furnaces and other smelting operations. Our electrodes come in four distinct types: RP Graphite electrodes, HP Graphite electrodes, SHP Graphite electrodes, and UHP Graphite electrodes.

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
