eaf graphite electrode
Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. It will experience calcining, burdening, kneading, forming, baking and pressure impregnation, graphitization and then precision machined with professional CNC machining. such products own characteristics of low resistivity, good electrical conductivity, low ash, high compact structure, good anti-oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.
Products Scope:
Regular Power graphite electrode
Impregnated (High density) electrode
High power graphite electrode
