Classification of graphite electrodes
A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.
A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.
A graphite electrode coated with an antioxidant protective layer (graphite electrode, antioxidant). The utility model has the advantages of forming a protective layer capable of conducting electricity and resisting oxidation at high temperature, reducing electrode consumption (19%~50%) during the steelmaking process of the poly carbon graphite electrode, prolonging the service life of the electrode (22%~60%), and reducing the electric energy consumption of the electrode. The popularization and use of this technology can bring about such economic and social effects:The unit consumption of graphite electrode is less, and the production cost is reduced.The power consumption of the graphite electrode is less, the energy consumption per unit of steelmaking is saved, the production cost is saved, and the energy saving is saved.Because the number of graphite electrodes is changed less, the labor quantity and danger coefficient of operators are reduced, and the production efficiency is improved.Graphite electrode is a kind of low consumption and low pollution product. It has a very important social significance in today's energy saving, emission reduction and environmental protection.
Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.
