Graphite electrodes buyers come from so many countries. They search for the Uhp, Hp, Rp graphite electrodes manufacturers from the areas with the low prices and the high quality. Different graphite electrode company own the same manufacturing processing, but the products quality may have a big difference. Rongsheng Company is a graphite electrode manufacturer in china, provide customers with high quality electrodes and nipples, as well as the technical induction both in the uses and the selections. You can get the more details about the graphite electrodes buyers attentions lists.
Attentions should be paid during using graphite electrodes
Although the purchaser has got the high quality graphite electrode, this does not mean that there will be no failure during the use of the graphite electrode. Rongsheng Company reminds buyers of graphite electrodes to pay attention to the following matters during graphite electrode use.
Proper grade and diameter of electrodes should be selected accordingto electric furnace capacity and transformer capacity.

When loading materials electric furnace, to reduce the collisionwith electrode during furnace load collapse, large block material should be loaded at the bottom side of EAF, meanwhile, don’t put lime and other electricity insulating material at right under the electrode, or it will affect electricity conductivity or break the electrode.
Pay attention to the position of furnacecover, if furnace cover is not in position, during the lifting and descending of electrodes, it can collide with the electrode and cause damages.
Well connected electrodes should not be horizontally placed to avoid rupture.
When connectingelectrodes, if there is shell off phenomenon of nipple pin, it should be added, and then the connection can be carried out.
If gaps is found after the connection of electrodes, the reasons must be checked and found, the electrodes can be normally used after the eliminationof gaps.
The electrodes should be vertically used, tilting operation should be avoided.
Clamp holder should be placed out of the alarm line. (note: clamp holder should not clamp at alarmline zone ,or the middle of the electrode, as it is easy to cause the rupture of the electrode)
As differentmaterials and different production crafts are adopted by different manufacturers, the physiochemical indexes of electrodes produced by different factories have some difference. So, don’t connect electrodes or nipples produced by different producers during using.
For electric arc furnacewith large vibration, pins can be used to prevent the loosening of electrodes.
