UHP graphite electrodes play a critical role in high-temperature processes related to metallurgy, metal refining, and alloy production, providing efficient electrical conductivity and outstanding resistance to high temperatures.
Graphite electrode brief introduction
Graphite electrode is made from domestic first-class petroleum coke and high quality needle coke and are widely used in electric arc furnaces for the production of alloy steels, metal, and other nonmetallic materials, etc. The Graphite electrodes include regular power, high power, ultra-high power, and square electrodes. The range of diameters covers from 250mm to 700mm.
Our products have the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, and high machining accuracy.

Attrition rate
The rate at which UHP graphite electrodes are consumed in an EAF depends on the steelmaking or other raw materials used, the grades of steel being produced, and the amount of supplemental (chemical) energy used. EAFs typically consume electrodes at a rate of around 2kg per tonne of steel produced, with some specialty steel applications consuming at a slightly higher rate.
