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 steels, metal and other
nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to
700mm. 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.
Applications
Used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.
Programmable properties
1.Good electrical conductivity
2.High resistance to thermal shock
3.High mechanical strength
Grades:RP, RPI, HP, SHP, UHP
