PRODUCT DESCRIPTION

Graphite electrode, mainly made of high quality petroleum coke and needle coke, coal tar pitch as binder, is prepared by calcination, compounding, kneading, pressing, roasting, graphitization and machining. According to the quality, it can be divided into regular power, high power and ultra high power.

APPLICATION

Ultra high-power graphite electrodes are mainly used in steel smelting process utilizing large capacity EAF (Electric Arc Furnace) and in LF (ladle refining furnace). The UHP electrodes are impregnated with special pitch in the furnace to increase their strength and density.
