Graphite Electrode suppliers DESCRIPTION: Graphite Electrodes are a high
temperature resistant graphite conductive refractory material used in the
metallurgical industry. Graphite Electrodes are made of petroleum coke,
bituminous coke as aggregates, coal tar pitch as binders, after raw material
calcination, crushing and milling, batching, kneading, molding, roasting,
impregnation, graphitization and machining, which are also known as artificial
graphite electrodes in order to distinguish from natural graphite electrodes
made of natural graphite. FEATURE: Low resistivity High temperature strength
Good thermal conductivity and electrical conductivity Low thermal expansion
coefficient Low ash, its ash content is controlled within 0.3%. Dense and equal
structure, Low graphite electrode consumption. Good oxidation resistance High
mechanical strength Needle coke content accounts for 80% for UHP Grade, raw
materials imported from Japan and South Korea APPLICATION: 1. Electric arc
steelmaking furnace. 2. Ladle arc refining furnace. 3. Ore-heating furnaces. 4.
