UHP GRAPHITE ELECTRODE
Ultra-high power(UHP) graphite electrodes, are ideal choice for utra-high power electric arc furnaces(EAF).They can also be used in ladle furnaces and other forms of secondary refining processes.UHP graphite electrodes’ current density is allowed more than 25A / cm2.
- Good conductivity
- Low resistivity
Description
With the continuous development in electric arc furnaces and ladle technology, the need for high-quality graphite electrodes has been on the rise.
The large diameter over 500mm UHP graphite electrodes are essential components for large capacity ultra-high power arc furnaces which are able to handle higher currents and provide more stability and lead to greater efficiency and lower costs in modern steelmaking and metallurgical industries.
Gufan Carbon is contributing to produce UHP graphite electrode a highly flexible option that can be tailored to meet the specific needs of our customers.
UHP Graphite Electrode Features
- High current carrying capacity
- High mechanical strength
- High resistance on thermal and mechanical shock
- High mechanical strength, low resistance
- Good electric and thermal conductivity
- High oxidation resistance, low consumption
- Good dimension stability, not easy to deform
- High machining accuracy and nice surface finishing
Mainly Application
Graphite Electrodes are widely used in LF, EAF, SAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.
- DC electric arc furnace(DC EAF)
- AC electric arc furnace(AC EAF)
- Submerged arc furnace (SAF)
- LF (ladle furnace)
- Resistance furnace
