UHP 600x2400mm Graphite Electrodes for Electric Arc Furnace EAF

Short Description:

UHP graphite electrodes are an essential material for electric arc furnace (EAF) steel making. UHP graphite electrode can provide a conductive path for the electric arc, which melts the scrap steel and other raw materials inside the furnace.

Surface Quality Ruler

  • 1.The defects or holes should not more than two parts on the graphite electrode surface, and the defects or holes size not be allowed exceed the data in table below mentioned.
  • 2.There is no transverse crack on the electrode surface.For longitudinal crack,its length should be not more than 5% of the graphite electrode circumference,its width should be within 0.3-1.0mm range.Longitudinal crack data below 0.3mm data should be negligible
  • 3.The width of he rough spot(black) area on the graphite electrode surface should be not less than 1/10 of the graphite electrode circumference,and the length of rough spot(black) area over 1/3 of the graphite electrode length is not be allowed.

      Description The graphite electrode nipple is a small but essential part of the EAF steelmaking process. It is a cylindrical-shaped component that connects the electrode to the furnace. During the steelmaking process, the electrode is lowered into the furnace and placed in contact with the molten metal. Electrical current flows through the electrode, generating heat, which melts the metal in the furnace. The nipple plays a crucial role in maint...
