Graphite Electrode UHP200mm Used for Steelmaking, Smelting

UHP Graphite electrodes  are mostly made of 100% high-specification needle coke, which is calcined, kneaded, pressed, roasted, graphitized and machined. 
Compared with  HP  and RP grades, UHP electrode requires highest technical expertise in each of the main process steps in making them, particularly baking, extrusion and graphitizing. The electrodes come with a wide range of sizes, but diameter of  600mm and 700mm high performance. UHP graphite electrode is often used for ultra high power electric arc furnaces (EAF) with current density greater than 25 A/cm

1.When loading the charge into the electric furnace,in order to reduce the impact on the electrod when the charge collapses,the big bulk material should be placed near the central bottom of the electric furnace,and at the same time,be careful not to use a large amount of non-conductive objects such as lime to accumulate directly under the electrode,which affecting the power supplying or breaking the electrode.
2.Should pay attention to the position of the furnace cover.If the furnace cover deviateds the electrodes rubs against the furnace cover,it will result in electrode damage and scraping when the elcetrode rises of falls.
3.When connecting the electrodes,first blow the dust in the nipple hole with compressed air,then align it with the center,and slowly screw it in vertically.The force used when screwing the nipple into the electrode hole should be smooth and average and the tightening torque should comply with the regulations.Before the ends of the two electrodes are in connected,blow off the dust again with compressed air and then tighten. 
4.During the electrode connection,the upper and lower branch electrodes should be kept vertical,and the upper branch electrode is aligned with the center line and slowly screwed into to prenent the damage to the thread and affect the connection effect.
5.When connecting the electrode,if it is found that the nipple bolt is detached,the joint bolt shoud be replaced and then connected.
6.After the electrode is connected,if it is found that there is a gap,it is necessary to find out the reasons so that can be used afater eliminating the connection gap.
7.When holding the electrode, the holder must avoid the joint area and donnt hold the electrode within the cordon line,
8.The electrode should be used vertically to avoid tilting operation.
9.The electrode should not used as carbon adding material to prevent from deterioration of electrode performance.
10.Due to the different raw materials and manufacturing processes used by different manufacturers,the physical and chemical properties of the electrodes and nipples are different.Therefore,generally it is not allowed to usd different manufacturers' nipples and electrodes in series.
11.The furnace cover should be well sealed to reduce the amount of air entering.The combustion-supporting nozzle and oxygen should be properly used to reduce the oxidation consumption at high temperatures.
12.For electric furnaces with large vibration,the method of applying the pins can also be adopted to prevent threads loosening and releasing.
13.The electrode and nipple end threads are of three threads per inch and four threads per inch.Pay attention to the type of threads end of the life spreader when using.The number of threaded type of the nipples and electrodes end types should match each other.
