I plant the production of high-power graphite electrode, ultra-high power graphite electrode. Raw materials selected high-quality needle-shaped coke through high-pressure molding, calcination, graphite, machining, such as a set of production. Suitable for steel mills, foundries, smelters, with low resistance, high resistance strength, high density, low ash and other advantages, our factory graphite products have antioxidant, low ton consumption and other advantages.
Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity ,thermal conductivity ,high mechanical strength, oxidation and corrosion resistance in high temperature .Graphite electrode is typically used in EAF (for smelting steel),submerged arc furnace (for producing ferroalloy ,pure silicon, phosphor, matte ,calcium carbide ,etc. And electric resistance furnace ,such as graphitization furnace producing graphite electrodes, glass-melting furnace ,electric furnaces producing carborundum, etc.
Graphite electrodes are classified into RP,HD,HP and UHP.

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.
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.
