81263 is a form of graphite electrode used in electric arc furnace steel making, and is a high quality, high-cost electrode with a wide application field. It is mainly used for smelting precipitation of ferroalloys, high temperature smelting of non-ferrous metals, smelting of various rare metals, and often as an electrode for smelting precipitation of some high-temperature special steel.

The working principle of 81263 is mainly based on the principle of electric arc. When a current is passed through the gap of two metal electrodes in a vacuum, a large amount of heat is generated, which is called electric arc. The 81263 electrode itself acts as a heat source when arc is needed, and the current produced during the arc melting process makes the metal ions enter the liquid state and enter the melting liquid.

81263 graphite electrodes have many characteristics, such as good electrical conductivity, low thermal expansion coefficient, high mechanical strength and good thermal shock stability. All of these characteristics combine to make them very suitable for electric arc furnace steel making. The reason is that when steel smelting, they can bear high current density and high temperature, so that the smelting process can be completed in a shorter time; owing to its superior mechanical properties, its service life is longer; and these electrodes are more efficient in energy consumption than other electrodes.

Due to its low thermal expansion coefficient, 81263 graphite electrode has strong resistance to thermal deformation and better thermal shock stability. When arcing, the electrode temperature is mostly uniform throughout its length, thus reducing the possibility of breakage. In addition, 81263 graphite electrode has excellent air permeability and high strength. When the electrode is inserted into the furnace, it can penetrate quickly and firmly without causing much resistance. It is more reliable than ordinary graphite electrodes.

In summary, 81263 graphite electrode has strong application fields and excellent working principles. It has a lower thermal expansion coefficient and high mechanical strength, thus making it very suitable for electric arc furnace steel making. Its excellent air permeability and high strength, and the fact that it can reduce the possibility of breakage due to its uniform temperature distribution throughout its length, all contribute to its efficient and reliable use. Thus, 81263 graphite electrode is a widely used electrode in electric arc furnace steel smelting and is well worth the high costs associated with it.
