Description



Product Details


Graphite electrode product


Graphite electrode is made of high quality calcined petroleum coke,imported needle coke and modified coal asphalt,the grade are RP,HD(impregnation),HP and UHP graphite electrodes,the specification is Ø75-700mm.

Graphite electrode produced by our company 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,etc.

Graphite electrode is widely used to smelt the steel,alloy steel and other metal or nonmetal material in electric arc furnace.
