A graphite electrode coated with an antioxidant protective layer (a graphite electrode antioxidant). Forming both conductive and high-temperature oxidation protection layer, reduce the electrode consumption (19%~50%), prolong the service life of the electrode (22%~60%), reduce the electric energy consumption of the electrode. The use of this technology can bring about such economic and social effects:
1. Graphite electrode unit consumption is less, production cost has a certain reduction. For example, a steel-making plant, according to the whole year does not occur discontinued a LF refining furnace 35 graphite electrode per week, refining treatment 165 furnace consumption calculation, the use of graphite electrode antioxidant technology, each year can save 373 (153 tons) electrode, each ton of ultra-high power electrode 16,900 yuan calculation, can save 2.5857 million yuan.
2. Graphite electrode consumes less energy, saves the unit steelmaking electricity consumption, saves the production cost, energy-saving!
3. Because graphite electrode exchange is less, it is less labor and risk coefficient of workers, improve production efficiency.
4. Graphite electrodes are low consumption and lower pollution products, in the energy-saving and emission reduction environmental protection advocates today, has a very important social significance.
This technology is still in the domestic research and development stage, and some domestic manufacturers also began to produce. In Japan and other developed countries have been more widely used. At present, there is also a special import of this antioxidant protection coating company.
