Production
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.
so it is the best conductive material for electric arc furnace and smelting furnace.
Applications
Graphite electrode is typically used in EAF (for smelting steel),submerged arc furnace (for producing ferroalloy ,pure silicon, phosphor, matte ,calcium carbide ,etc. And electric resistance furnace. ,such as graphitization furnace producing graphite electrodes, glass-melting furnace ,electric furnaces producing carborundum, etc.
Programmable properties
such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength.
