Ultra-high Power (UHP) Graphite Electrode

Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binding agent, calcination, batching, kneading, pressing, roasting, graphitization, and machining.

Graphite electrode is a conductor that releases electric energy in the form of electric arc to heat and melt the charge in the electric arc furnace. It has the characteristics of low resistivity, good conductivity, low ash, compact and uniform structure, good oxidation resistance, and high mechanical strength.

Description

Our graphite electrode products have strict consumption control, low resistivity, low ash content, high temperature strength, low thermal expansion coefficient, good thermal conductivity and electrical conductivity, compact structure, high oxidation resistance, high mechanical stability and other significant advantages. Its content of UHP needle coke is up to 80%, and raw materials are imported from Japan and South Korea. The UHP graphite electrodes suit the operating conditions of modern arc furnaces and those main properties are of decisive importance for obtaining economical consumption rates.

Application of Graphite Electrode

  1. Graphite electrode is being used in electric arc steelmaking furnace Graphite electrode is mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. A strong current generates an arc discharge through the gas at the lower end of the electrode, and uses the heat generated by the arc to smelt.
  2. Graphite electrode is being used in ore-heating furnaces Graphite electrode ore-heating furnaces are mainly used to produce ferroalloys, pure silicon, yellow phosphorus, matte and calcium carbide, etc., which is characterized by electrical conductivity.
  3. For resistance furnaces, graphitization furnaces for producing graphite products, melting furnaces for melting glass, and electric furnaces for producing silicon carbide are all resistance furnaces.
  4. Used for processing a large number of graphite electrode blanks; also used for processing into various crucibles, graphite boats, hot die casting molds and heating elements for vacuum electric furnaces, etc.
