Advantages of Graphite Electrode
* Good oxidation resistance
* High mechanical strength.
* Needle coke content accounts for 80%
* Low electrical resistivity,good electrical conductivity
* Low ash content,Its ash content is controlled within 3%
* Dense and uniform structure,Low graphite electrode consumption
* Annual output of 80,000 tons, timely delivery
Application:
Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking,Yellow phosphorus furnace , Industrial silicon furnace or melting copper. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment.High Quality Needle Coke in HP&UHP graphite electrode,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
