RP graphite electrode (RP): It is allowed to use graphite electrode with current density lower than 17A/cm2, which is mainly used for ordinary power electric furnaces such as steel making, silicon refining, and yellowing phosphorus.
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. such of the products own characteristics with low resistivity, good electrical conductivity, low ash, compact structure, good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace,ladle furnace and submerged arc furnace.
Normal tolerance (default): tolerance of ±10mm diameter and length ±100mm.
Fixed tolerance: tolerances of 3-5 mm in diameter and 10-30 mm in length.
