Rongsheng Graphite Electrode
Graphite electrodes are characterized by low resistance, good electrical conductivity and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc. According to its high quality and low quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
Graphite Electrodes Application
1.For arc furnaces of electric arc furnaces. Graphite electrodes are most often used in a coal-smelting electric furnace.
2.For a closed arc
3.For a resistor furnace
4.For the production of graphite shaped products. The graphite electrode blank is also used for processing in various crucibles,shapes, boats and heating elements and other graphite products
Graphite Electrodes Advantages
1.Anti-oxidation treatment for longevity.
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.
