Why choose us

Graphite electrodes are used in the electric smelting industry and have properties such as superconductivity, thermal conductivity, high mechanical strength, oxidation resistance, and high-temperature corrosion resistance.

Our graphite electrodes have low resistance, high density, high oxidation resistance, and precise machining accuracy, especially low sulfur and low ash, which will not bring secondary impurities to the steel.

Graphite has good chemical stability. Specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability.



Application of graphite electrode

 The graphite electrode raw material adopts low sulfur and low ash CPC. Add 30% needle coke to the HP grade electrode of the coking plant asphalt. UHP grade graphite electrodes use 100% needle coke and are widely used in LF. Steel making induction furnace, non-ferrous metal induction furnace. Silicon and phosphorus industries.
