Ordinary power graphite electrode
Graphite electrodes with current density less than 17A /cm2 are allowed, mainly used in steelmaking, silicon smelting, yellow phosphorus smelting, etc.
Oxidation resistant coated graphite electrode
① Graphite electrode is coated with antioxidant protection (graphite electrode antioxidant).It can reduce electrode consumption (19% ~ 50%), prolong service life (22% ~ 60%), and reduce electrode power consumption.The popularization and application of this technology can bring such economic and social benefits.
The single consumption of graphite electrode is less, and the production cost is reduced to a certain extent.If the one-level LF refining furnace does not stop production all year round and consumes about 35 graphite electrodes per week, 165 furnaces are refined and treated with graphite electrode anti-oxidation technology, 373 electrodes (153 tons) can be saved every year, and 2,585,700 yuan of ultra-high power electrodes can be saved per ton 16,900 yuan per year.
② The graphite electrode consumes less electricity, saving unit steelmaking power consumption, saving production cost, saving energy!
③ Due to the low number of graphite electrode replacement, the operator's labor and risk factors are reduced, and the production efficiency is improved.
④ Graphite electrode is a kind of low consumption and low pollution product.It is of great social significance in energy conservation, emission reduction and environmental protection.
High power graphite electrode
Graphite electrodes are mainly used in high-power arc furnaces for steelmaking with permissible current density of 18 ~ 25A/cm2.
Ultra high power graphite electrode
Graphite electrodes with current densities greater than 25A/cm2 are allowed.Mainly used for ultra high power electric arc furnace.
