Graphite Electrode Use Aug 07, 2018

(1) Ordinary power graphite electrode allows the use of current density of less than 17a/cm 2 graphite electrodes, mainly used in steelmaking, silicon refining, such as the ordinary power furnace.

(2) Anti-oxidation coating graphite electrode A graphite electrode coated with an antioxidant protective layer (graphite electrode antioxidant) on the surface. The formation of conductive and high-temperature oxidation of the protective layer, reduce the electrode consumption (19%~50%), prolong the service life of the electrode (22%~60%), reduce the electric energy consumption of electrodes.

The use of this technology can bring about such economic and social effects as: 

① Graphite Electrode unit Consumption is less, the production cost has a certain reduction. For example, a steelmaking plant, according to the annual production failure of the first-level LF refining furnace about 35 graphite electrode per week, refining treatment of 165 furnace consumption calculation, the use of graphite electrode antioxidant technology, the annual savings of 373 graphite electrode (153 tons) electrode, each year, ultra-high power electrode of 16,900 yuan per million calculation,

Can save 2.5857 million yuan.

② graphite electrode consumes less electric energy, economize the unit steelmaking electricity consumption, economize the production cost, save energy!

③ because the graphite electrode exchange is less, the workers ' labor and risk coefficient are less, and the production efficiency is improved.

④ Graphite Electrode is a high consumption and high pollution products, in energy conservation and environmental protection advocated for several days, has a very important social significance. This technology is still in the domestic research and development stage, but also some domestic manufacturers also began production. In Japan and other developed countries have been more widely used. At present, there is a special import of this antioxidant protection coating companies.
