It should also be noted that among the three high-temperature composite materials including graphite electrodes, graphite molds, and graphite crucibles, graphite materials are prone to oxidation and combustion reactions at high temperatures, resulting in a loose carbon layer on the surface of the plastic material and an increase in porosity. Graphite electrodes are important carbon products made of petroleum coke and pitch coke as aggregate materials and coal tar pitch as binder. They are used in electric arc steelmaking furnaces, ore-smelting furnaces, and other equipment, and have properties such as electrical conductivity, high-temperature resistance, and thermal shock resistance. The manufacturing process is rigorous and diverse, requiring selection based on actual needs. Graphite electrodes are widely used in metallurgy, chemical industry, and other fields, emphasizing environmental protection and resource utilization, and are of great significance to industrial development.

Production Application:
- 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
- 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
- Produce key industrial materials: Manufacture metallurgical-grade silicon, polysilicon (for solar energy/semiconductors), as well as phosphorus and ferroalloys in submerged arc furnaces
- 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
- Support specialized industries: Assist in high-temperature production of glass/ceramics (reducing energy consumption); also used in laboratory high-temperature experiments and electrochemical analysis
