High quality high power graphite electrode for ladle furnace
Descrizione
High quality graphite electrode
Graphite electrode, mainly use petroleum coke, needle coke for material, and use coal pitch for binder, after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization and then precision machined with professional CNC machining.
Graphite electrode has the advantages of low resistivity,high electrical conductivity and thermal conductivity,good oxidation resistance, good thermal shock resistance,high mechanical strength,easy to machine,eccetera.
