Graphite electrode manufacturers can reduce the consumption of electrodes during steelmaking and extend the service life

by ray / Tuesday, 09 November 2021 / Published in blogs

The anti-oxidation coating graphite electrode produced by graphite electrode manufacturers refers to the graphite electrode coated with an anti-oxidation protective layer (graphite electrode antioxidant). The anti-oxidation coating forms a protective layer that can conduct electricity and resist high temperature oxidation, which can reduce electrode consumption (19% – 50%), prolong the service life of graphite electrode (22% – 60%), and reduce the electric energy consumption of electrode. The anti-oxidation coating graphite electrode can bring such economic and social effects:

① If the unit consumption of graphite electrode is less, the production cost will be reduced. For example, a steelmaking plant can save 373 (153 tons) electrodes per year, 16900 yuan per ton of ultra-high power electrodes per year, and 2585700 yuan per ton of ultra-high power electrodes per year, if the consumption of about 35 graphite electrodes per week and 165 refining furnaces per week is calculated according to the consumption of the first level LF refining furnace that has not been shut down in the whole year.

② The graphite electrode consumes less power, saving the electricity consumption per unit of steel-making, saving the production cost and energy saving!

③ Due to the less times of changing graphite electrode, the labor volume and risk coefficient of operators are reduced, and the production efficiency is improved.

④ Graphite electrode is a low consumption and low pollution product, which has very important social significance in today’s energy conservation and emission reduction.

This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies specialized in importing this kind of anti-oxidation protective coating in China.
