Uses and Properties of Graphite Electrode

Classification of graphite electrodes

Regular power graphite electrode (RP); High power graphite electrode (HP); Standard-ultra high power graphite electrode (SHP); Ultra high power graphite electrode (UHP).

1. Used in electric arc steelmaking furnace

Graphite electrode materials can be mainly used in electric furnace steelmaking. Electric furnace steelmaking is to use research graphite electrodes to introduce working current into the furnace. The strong current can generate arc discharge through these gas environments at the lower end of the electrodes, and use the heat generated by the arc to smelt. The size of the capacitance, equipped with graphite electrodes having different diameters, can be used continuously for the electrodes, abutting against the connection between the electrodes on the electrode joints. Graphite used in steelmaking as an electrode material accounts for about 70-80% of the total graphite electrode consumption in China

2. Used in submerged heat electric furnace

It is mainly used in the production of iron furnace ferroalloy, pure silicon, yellow phosphorus, calcium carbide and matte. It is characterized in that the lower part of the conductive electrode is buried in the charge, so that in addition to the heat generated by the arc between the electric plate and the charge, the current passes through the charge Heat is also generated by the resistance of the charge.

3. Used in resistance furnace

In the production process, graphitization furnaces for graphite material products, melting furnaces for melting technical glass and production, and electric furnaces for silicon carbide are all resistance furnaces. The material management in the furnace is not only a heating resistor, but also a heated object.

4. Special-shaped products such as hot pressing molds and heating elements of vacuum electric furnaces

It should also be noted that among the graphite materials in the three high-temperature composite materials including graphite electrodes, graphite molds and graphite crucibles, at high temperatures, among the three graphite materials, graphite is easy to oxidize and burn, so that the carbon layer of the plastic material on the surface , Improve the porosity and loose structure of life.
