China UHP 500 * 2100mm Graphite Electrode for Eaf

China UHP 500 * 2100mm Graphite Electrode for Eaf

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite electrodes include: regular power,high power,ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics:low electric resisitivity, good electric and thermal conductivity,high oxidation resisitance, greater resisitance to thermal and mechanical shock,high mechanical strength, high machining accuracy.
We can produce regular power, high power, and ultra high power graphite electrodes of Φ300-800mm according to customers requirements.

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.

EAF Graphite Electrode PRODUCT DESCRIPTION

Graphite electrode, mainly made of high quality petroleum coke and needle coke, coal tar pitch as binder, is prepared by calcination, compounding, kneading, pressing, roasting, graphitization and machining. According to the quality, it can be divided into regular power, high power and ultra high power.
