Detailed Description


Our factory has basically eliminated small and medium-sized electric furnace, my company's production of steel mills currently use a lot of diameter 550-700mm of high power or ultra high power graphite electrode more, dc furnace is also designed by high power or ultra high power.
At the beginning of the 21st century, our annual capacity of graphite electrode has reached about 100,00 t. Due to the rapid development of the technology of electric steelmaking industry, the high power electric furnace, ultra-high power electric furnace and dc electric furnace are becoming more and more popular.
Graphite electrode is an important high-temperature conductive material for electric furnace steelmaking.electric energy is input to electric furnace through graphite electrode, and the high-temperature arc generated between electric extreme part and furnace charge is used as heat source to melt metal for steelmaking.some other electric smelting equipment (such as submerged arc furnace) also use graphite extremely conductive material. The excellent physical and chemical properties of graphite electrode have been widely used in other industrial sectors. At present, the carbon products industry, which mainly produces graphite electrode, has become an important part of the raw material industry.
 

Size of RP graphite electrode

  • 1.300-500mm
  • 2.550-600mm
     

Features Of RP Graphite Electrode

Regular power graphite electrode, produced by ordinary grade petroleum coke.
RP graphite electrode has a low graphitization temperature, so its physical and chemical properties are poor,
Such as high resistivity, large linear expansion coefficient, poor thermal shock resistance, and less allowable current density.
