UHP Grade Graphite Electrode With High Density For Steel Plant
Production Description:
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 and
smelting furnace.
Graphite electrodes are used mainly in ladle furnaces,electric-arc
furnace steelmaking,Yellow phosphorus furnace , Industrial silicon
furnace or melting copper. They are presently the only products
available that have the high levels of electrical conductivity and
the capability of sustaining the extremely high levels of heat
generated in this demanding environment.High Quality Needle Coke in
HP&UHP graphite electrode,ensure the electrode application is
perfect. Graphite electrodes are also used to refine steel in ladle
furnaces and in other smelting processes.
