Application:
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 the 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,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
Properties:
1. Good electrical conductivity.
2. Strong thermal shock resistance.
3. High mechanical strength.
Variety:
1. RP (Regular Power)
2. HP (High Power)
3. UHP (Ultra High Power)
4. RPI (Regular Power Impregnated)
(Notice: All of Graphite Electrodes is equipped to tapered nipple
2.High-purity,high-density,strong chemical stability.
3.High machining accuracy,good surface finishing.
4.High mechanical strength,low electrical resistance.
5.Resistant to cracking & spalling.
6.High resistance to oxidation and thermal shock.
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
