Product Description

UHP Grade Graphite Electrode Manufacturer Electric Arc Furnace Electrodes​

 

 

Description:

Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar as binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electric energy in the form of arc in an electric arc furnace to heat and melt the charge. According to their quality indicators, they can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes.
The main raw material for the production of graphite electrodes is petroleum coke. A small amount of asphalt coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and asphalt coke cannot exceed 0.5%. Needle coke is also required when producing high power or ultra-high power graphite electrodes. The main raw material for the production of aluminum anodes is petroleum coke, and the sulfur content is controlled to be no more than 1.5% to 2%. Petroleum coke and asphalt coke should meet the relevant national quality standards.

Production Application:

  1. Core application in Electric Arc Furnace (EAF) steelmaking (accounting for over 70% of global consumption): Conduct electricity to generate high-temperature electric arcs for melting scrap steel, producing construction steel, automotive steel and specialty steel
  2. Facilitate non-ferrous metal smelting: Smelt metals such as copper, nickel and lead; also used in vacuum remelting of refractory metals like titanium to achieve purification and uniform composition
  3. Produce key industrial materials: Manufacture metallurgical-grade silicon, polysilicon (for solar energy/semiconductors), as well as phosphorus and ferroalloys in submerged arc furnaces
  4. Serve the electrochemical industry: Act as anodes in electrolytic refining of metals like copper and gold for purification, or as current collectors in fuel cells to ensure stable electricity transmission
  5. Support specialized industries: Assist in high-temperature production of glass/ceramics (reducing energy consumption); also used in laboratory high-temperature experiments and electrochemical analysis
