Product Description

RP/HP/UHP Graphite Electrode Supplier for Silicon Metal Production​

 

Description:

Graphite electrode raw materials use the domestic petroleum coke and pitch coke and imported Japanese needle coke .HP grade graphite electrode contain 30% imported needle coke. UHP graphite electrode contain more than 80% imported needle coke. They are widely used in electric arc furnace(EAF), ladle furnace(LF) for the production of alloy steel, metal and nonmetallic materials. They are characterized by low resistance, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc

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
