The main properties of graphite electrode
Graphite electrode with current density less than 17a/ cm 2 is allowed. It is mainly used in common power electric furnace for steelmaking, silicon refining, yellow phosphorus refining, etc.
A graphite electrode coated with an antioxidant protective coating (graphite electrode antioxidant). To form a protective layer that can conduct electricity and resist high temperature oxidation, reduce the electrode consumption (19%-50%) in the process of making steel, prolong the service life (22%-60%) of the electrode, and reduce the electric energy consumption of the electrode. The widespread use of this technology can bring about such economic and social effects as:
- The graphite electrode unit consumption is less, the production cost has a certain reduction.
- graphite electrode consumption of less energy, save unit steelmaking electricity consumption, save production costs, energy saving.
- As a result of the graphite electrode change times are less, the operation of less labor and risk factors, improve the production efficiency.
- graphite electrode is a low consumption and low pollution products, in the promotion of energy conservation, emission reduction and environmental protection today, has a very important social significance.properties of graphite electrode
Graphite electrodes with a current density of 18 to 25a/ cm 2 are allowed, mainly for high-power arc furnaces used for steelmaking.
Graphite electrodes with current density greater than 25a/ cm 2 are allowed. Mainly used for ultra high power steel arc furnace.
