UHP extruded graphite electrodes rods with nipples
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.

Operating instruction
1. Use special hoist tools to hoist graphite electrode. It is strictly forbad to prize electrode ends up with crowbar. It must be handled with great care during transport to avoid being struck.
2. Graphite electrode must be kept away from being moistened or wetted by rain, snow and water, and must be kept dry.
3. Carefully checking before making connection, make sure that socket and nipple thread is not damaged, nipple pitch plug is in.
4. Blow the nipple and socket threads with compressed air.
5. It must be dried in the furnace before use, the drying temperature in the furnace should be less than 150℃,the drying period should be more 30 hours
6. Graphite electrode must be connected and contacted closely and straightly.Use moment spanner for connecting electrode with suitable force. Mustn’t decline.
7. The holding device must hold the electrode tightly, good contact and no arc.
8. To avoid the electrode breakage, put the large materials in lower part and small materials in the upper part. Insulating materials should not be put into the furnace. The working current of electrode must be conformity with the allowable current of electrode in the instructions.
