450*2400mm UHP450 Electric Arc Furnace Graphite Electrode
450*2400 mm , 450*2100 mm and 450*1800 mm Electric Arc Furnace Graphite Electrode
Introduction
Graphite electrode is the conducting element which is largely used in steel-making industry. It is made of petroleum coke, needle coke,coal pitch and produced by a series of strict production processes. After power on, graphite electrode will generate electric arc which can releases electric energy to heat the material inside furnace.
Graphite Electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch. After calcining,burdening, kneading, extruding, baking, impregnation, graphitization and then machined with professional CNC machining.The products own characteristics of low resistivity, good electrical conductivity, low ash content, compact structure, good anti-oxidation and high mechanical strength. It is widely used in LF, EAF for steel making industry, non-ferrous industry, silicon and phosphorus industry. So it is the best conductive material for electric arc furnace and smelting furnace so far.
