Product Description
Graphite Electrode is made from high quality calcined petroleum coke and high quality imported
needle petroleum coke. It is manufactured through the process of calcining, dosing, mixing,
forming, baking, impregnating, graphitization in a high temperature of over 3000°C, and then machining.
Grade: RP (EG), IP, HP, SHP, UHP
Diameter: 150mm--600mm
Length: 1800mm (+/-100mm), 1600mm (+/-100mm), 2100mm (+/-100mm)
Features
1. Low electrical resistance
2. High bulk density
3. Low ash content
4. High mechanical strength
5. High oxidation resistance for abrupt change of temperature and high-yield in melting process.
