Description de produit
HP SHP UHP Making Steel Graphite Electrode With Nipple
Graphite electrodes are used in both DC and AC electric arc furnaces. Steelmaking workshops have to cover the cost of these consumable electrodes during new steel producion process. So optimizing the usage of graphite electrodes is a cost-saving tactic. Full range of grades and sources to meet performance & cost needs. Grades include:
1.HP for foundries, Ladle Furnaces and Low Powered EAFs
2.SHP for Higher powered foundries and Ladle furnaces
3.UHP for high-performance Melt Shop EAFs
1.HP for foundries, Ladle Furnaces and Low Powered EAFs
2.SHP for Higher powered foundries and Ladle furnaces
3.UHP for high-performance Melt Shop EAFs
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.
Advantage:Graphite electrode is more and more widely used in the iron and steel industry.It makes less pollution and saves more power,it's good for our environment.The graphite electrode has long working-life,as it needn't to be changed often,that reduce the labor indensity of the works and avoid much danger.
Type:We can supply High purity graphite electrode.Regular power,high power and ultra high power graphite electrode can be supplied.Fine grained structral graphite electrode and oxidation resistant coating graphite electrode are provided.Any size could be requested by the customer.
Application:Mainly used for the electric arc furnace to smelt the molten steel and used for the refining furnace such as AOD VOD LF furnaces in the steel and non-ferrous metal metallurgy industry.
