Manufacturer Supply High Quality Carbon Graphite Electrode for Arc Furnace RP HP SHP UHP 250-450
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, graphitizationand then precision machined with professional CNC machining. such of the products own characteristics withlow 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 and smelting furnace.
According to its quality indicators, graphite electrodes can be divided into RP graphite electrodes, HP graphite electrodes and UHP graphite electrodes.
packing and shipping
The graphite electrode is packed in wooden frame, the graphite electrode and nipple are connected, lined with waterproof and dustproof plastic sheeting, the external steel belt is fastened, beautifully and firm, suitable for land transportation, railway and sea transportation.
Unconditional return is provided in case of quality problem by HP GRAPHITE to completely eliminate your worries!
