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. Mustnt 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.
UHP HP RP graphite electrode Φ400-700mm,length 1800mm 2100mm 2400mm 2700mm
The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. Graphite Electrodes has good electrical properties and chemical resistance, which has high mechanical strength at high temperature and good seismic performance.
China uhp hp rp graphite electrode for steel industry The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, forming, baking, graphitization and machining. According to its quality indicators, graphite electrodes can be divided into RP graphite electrodes, HP graphite electrodes and UHP graphite electrodes. Our factory produce: 1. RP graphite electrode 2. HP graphite electrode 3. UHP graphite electrode Needle coke material , Low ash , low consumption!
Carbon graphite electrode manufacturer, diameter:100-700mm, length:1500-2700mm,
Artificial graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization and then precision machined with professional CNC machining.such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace.
