Rongsheng Graphite Electrode
Size: Diameter ranges from 50 to 1200mm, Length from 1500 to 2400mm.
Application: Electric arc furnaces, ladle furnaces and submerged arc furnaces for steel making and yellow phosphorous production.
Grades Available: RP, HP, SHP, UHP graphite electrodes and nipples.
Special Treatment: Anti-oxidation impregnation treatment to prolong graphite electrodes service life and reduce consumption rate.
Graphite Electrodes Application
Graphite electrodes was commonly used in electric arc furnace and smelting furnace to smelting all kinds of alloy steel.
It also can be used in producing the industrial silicon, phosphor, quartz glass, corundum, rare earth and other industrial production.
Graphite Electrodes Advantages
1. Good machining performance
2. Easy electrode polishing
3. Small electrode consumption: good conductivity and low resistivity
4. Fast discharge speed
5. Light weight
6. High temperature resistance: the sublimation temperature is 3650"C, and the electrode does not soften under high temperature conditions
7. Small electrode deformation: the coefficient of thermal expansion is small, and the dimensional accuracy of discharge is improved
