Graphite Electrodes

Graphite  electrode, mainly in petroleum coke, needle coke as raw material, coal  tar pitch as binder, calcined, ingredients, mixed kneading, pressure,  roasting, graphitization, machining and made in the arc furnace in the  form of arc release Electric energy on the charge  heating and melting of the conductor, according to its quality  indicators can be divided into ordinary power, high power and ultra-high  power.


Graphite Electrode Classification
RP Graphite Electrode
Allows  the use of current density of less than 17A / cm 2 of the graphite  electrode, mainly for steel, silicon, boil yellow and other ordinary  power furnace.

HP Graphite Electrode
Allowing  the use of current density of 18 ~ 25A / cm 2 of the graphite  electrode, mainly for steel-making high-power electric arc furnace.

UHP Graphite Electrode
Allowing  the use of current density greater than 25A / cm 2 of the graphite  electrode, mainly for ultra-high power steel arc furnace.


Instructions for use
1, by the wet graphite electrode, before use to dry.
2, remove the spare graphite electrode hole on the foam protective cap, check the electrode hole thread is complete.
3, with no oil and water compressed air cleaning spare graphite  electrode surface and hole thread; to avoid the use of steel wire or  metal brush cloth cleaning.
4. Do not touch the threads by carefully screwing the joint into the  electrode hole at the end of the spare graphite electrode (it is not  recommended to insert the connector directly into the electrode that is  replaced on the furnace).
5, the electrode spreader (recommended the use of graphite material  spreader) screw into the electrode at the other end of the electrode  hole.
6,  lifting the electrode, the mat soft objects to the end of the alternate  electrode to meet the end of the connector to prevent the ground to  break the joints; with a hook into the spreader after the lifting ring,  lifting the electrode to be smooth, to prevent the electrode from the  B-loose Off or collide with other fixtures.
7,  the backup electrode hanging to the electrode to be connected to the  top of the electrode hole slowly after the fall; rotating spare  electrode, so that the screw hook and the electrode with the rotation  down; in the two electrode ends away from 10-20mm, again with compressed  air Clean the two ends of the electrode and the exposed part of the joint;  in the final complete discharge of the electrode, not too much, or due  to violent collision, will lead to electrode holes and joints of the  thread damage.
8.  Tighten the backup electrode with a torque wrench until the ends of the  two electrodes are in close contact (the correct connection of the  electrode and the connector is less than 0.05 mm).
