* Low graphite electrode consumption.
* Good oxidation resistance
* Needle coke content accounts for 80%,
1. Electric arc steelmaking furnace.
Quality Assurance & Control
· National Certified Laboratory
· Key testing instruments, including: specific resistor, bulk density meter, elasticmodulus meter, bending strength inspector, ash analysis meter, CTE analysis meter, etc.
· On-time instrument calibration
· On-site properties testing, including:
L-CTE,C-CTE
Specific resistance, bulk density,
Bending strength, ash content, elastic modulus
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
