Graphite electrode raw material use low sulphur and low ash CPC, coke plant pitch. HP grade graphite electrode add 30% Japan needle coke, UHP grade graphite electrode use 100% needle coke. Widely used in LF, EAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.
Graphite electrode is used in the electric smelting industry, which has properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature.
Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capacity, precise machining accuracy, especially with low sulphur and low ash will not give steel second time to impurity.
Graphite has good chemical stability. The specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability.
