Graphite electrode is mainly applied for metallurgy industry and calcium carbide, phosphor-chemical enterprise, such as iron and steel smelting, industrial silicon, yellow phosphorous ,ferroalloy, titania slag, brown fused alumina etc submerged-arc furnace melting production. Typical Properties of Large-size Graphite Electrode. Diameter:600mm-1400mm Length: 1850mm-2400mm 1600$-4050$ per ton Pakage:wooden Notice: 1. Electrodes should be stored in a clean and dry place avoiding vibration and collision. It should be dried before use . 2. When connecting the nipples, the user should clean the hole with compressed air and then screw the nipple into it carefully without damaging the threads. 3. Before the electrodes are connected, cleaning the electrode tip by the compressed air when the two electrodes are 20-30mm away. 4. When the electrodes are connected by the wrenches, it should be fully tightened to the specified location that the gap between the two electrodes is less than 0.05mm. 5. To avoid the electrode breakage, please keep away from the insulation material blocks. 6. To avoid the electrode breakage, place the aniseed block on the lower part and set the small block on the upper part.
