UHP Grade Refractory Products Graphite Electrode High Density For Steel Plant

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.

Instructions of usage for Graphite Electrode:

Notes of usage:

1.To Place the nipples, first use compressed air to clean the hole, then carefully screwed the nipples into it (do not damage the thread).

2.To connect the electrodes, when there’s 20-30mm distance between the two electrodes, using compressed air to clean the two extremes.

3.Connector locations should be selected c-map.

4.When use the wrenches to connect electrodes, should be fully tighten to specified torque.

5.To avoid electrode broken, please remove the insulating material in the furnace.

6.To avoid electrode broken, pls. place the big block in the lower and smaller block at the upper.

We can manafacture and export graphite electrodes in different grade ,shape and dimension.Whenever you need it ,please feel free to let us know.we promise you the top quality and lower price.
