Using petroleum coke and needle coke as raw materials, coal asphalt as binder, RP Graphite Electrode is made through the production process of calcination, compounding, kneading, pressing, roasting, graphitization and machining, which is the conductor that releases electric energy in the form of electric arc in electric arc furnace to heat and melt the furnace charge. The Graphite Electrode is mainly suitable for electric arc furnaces for steel making. Everyone who needs RP Graphite Electrode for smelting steel can Contact us for more details.

Remarks:
There should be less than two defects or holes on the electrode surface, the max size of which is mentioned in the above chart.
There should be no transverse crack on the electrode surface. For the longitudinal crack, the length should be less than 5% of the electrode circumference and the width in between 0.3~1.0mm.
The width of black area on electrode surface should be less than 1/10 of electrode circumference and the length less than 1/3 of electrode.
Select the appropriate RP Graphite Electrode grade and diameter according to the capacity of EAF and transformer.
Avoid damaging and moistening during the process of loading, unloading and storage. Wet electrodes should be dried. When lifting, needs to protect the electrode connector hole and the connector thread.
When connecting the electrode, use compressed air to blow off the dust in the connector hole. When the holder is holding the electrode, be sure to avoid the connector area.
The melting period is the most prone to break the electrode, so the operator should be carefully observed, timely lift the electrode.
In the refining period, if carbon is added by the RP Graphite Electrode, the electrode immersed in the molten steel becomes thinner quickly and breaks easily or causes the joint to fall, resulting in increased electrode consumption. Therefore, by other means to increase carbon as far as possible.
