UHP graphite electrode with graphite nipple for EAF/LRF of steel making 3tpi/4tpi/4tpil Nipple for Graphite Electrode From China Manufacturer


Graphite Electrode
 
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.

Notes of the use of graphite electrode

1.The electrode holder should be held in the place beyond the security line of the top electrode;otherwise, the electrode would be easily broken.the contact surface between the holder and the electrode should be cleaned up regularly to maintain a good contacting,the cooling jacket of the holder shall be avoided from water leakage.
2.Identify the reasons it there is gap in the electrode junction,do not use them until the gap is eliminated.
3.If there is falling off of nipple bolt when connecting electrodes,it is necessary to complete the nipple bolt.
4.The application of electrode should avoid of tilting operation, particularly , the gr.oup of connected electrodes should not be put horizontally so as to prevent from breaking.
5.When charging materials to the furnace,the bulk materials should be charged to the place of the furnace bottom,so as to minimize the impact of the large furnace materials on the electrodes.
6.The large pieces of insulation materials should be avoided of stacking on the bottom of the electrodes when smelting .so as to prevent from affecting the electrode use,or even broken.
7.Avoid of collapsing the furnace lid when rising or dropping the electrodes,which may result in electrode damage.
8.It is necessary to prevent the steel slag from splashing to the threads of the electrodes or nipple stored in the smelting site,which may damage the precision of the threads.
