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!
UHP 400mm*1800mm UHP 450mm*1800mm Used in steel, cement and glass manufacturing, expanded graphite - based sealing gaskets, graphite grease, braid, brushes, brake lining, etc.
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.
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.

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.
The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste. After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material. At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form. The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues. The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process. Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed. The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise. The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container. Please feel free to contact us for further details.
