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
