Graphite Electrode RP Description

Graphite electrode rp uses domestic petroleum coke and asphalt as raw materials, in accordance with the regular power graphite electrode production processes, calcination, dosing, kneading, forming, baking, graphite and machining refined. The nipple uses one time of impregnation and two time of baking processes.

Properties of Graphite Electrode RP

  • Good electrical conductivity,
  • High resistance to thermal shock ,
  • High mechanical strength,
  • For steel making electric arc furnace.

Advantages of Graphite Electrode RP

  • Excellent resistance to thermal shock and conduction,
  • Good wear resistance, good lubricity and long service life,
  • The surface can be used for the long life of anti oxidation treatment,
  • High temperature resistance, corrosion resistance, strong acid resistance.
