8mpa 200mm RPI Graphite Electrode For Smelting
China graphite electrode
Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steel, metal and other nonmetallic materials, etc. The graphite electrodes include regularpower, high power, super high power, ultra high power and square electrode. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

Graphite electrodes are used primarily in electric arc furnace steel manufacturing.
Graphite electrode can provide high levels of electrical conductivity and capability of sustaining the extremely high levels of generated heat.
Graphite electrodes are also used in the refinement of steel and similar smelting processes.
Graphite electrodes are also used in gouging operations such as in the forming of a bevel or groove, removing defects in castings or weldments by an arc or gas process. Arc gouging removes material by melting it with the heat of an arc struck between a carbon –graphite electrode and the base metal .compressed air or nitrogen simultaneously blows the molten metal away.
