Focusing
on the international market of graphite electrode, the company has a solid
economic foundation, a strong relationship network and
a
backbone team with the strong operation ability for our customers to
provide the stable
and reliable quality of products and professional, all-roundGraphite Electrode
Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke
and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization
and then precision machined with professional CNC machining.such of the products own characteristics with
low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.
