EG RP300mm graphite electrodes is in hot selling
Graphite electrode of RP300 specification is a very common general electric arc furnace steelmaking material. The graphite electrode of this specification has stable and reliable quality, low consumption and low breakage rate. The resistance of this specification is lower than 8.5 μΩ.m, and the length is generally 1800mm+/-100mm, or some customers need between 1500-1800mm.Graphite electrode raw materials use the domestic petroleum coke and pitch coke and imported Japanese needle coke
