Graphite electrode is made of mixed petroleum coke and needle coke as raw materials,and coal pitch as binder,to be extruded,baked,impreg
nated,graphitized and machined to use as conductive material on EAF (Electric Arc Furnace)and LF(Ladle Furnace),and has regular power
(RP)impregnated(lP),high power(HP)andultra-high power(UHP)four series.
