What are oxidation-resistant coated graphite electrodes, graphite electrodes for smelting, and ultra-high power graphite electrodes? I believe many people do not understand the advantages of graphite electrodes, especially graphite electrodes with anti-oxidation coating. Now, let us first understand the graphite electrode, and then have an in-depth understanding of the advantages of oxidation-resistant coated graphite electrode in steelmaking production.
Rongsheng Graphite Electrodes
Rongsheng graphite electrode mainly uses petroleum coke and needle coke as raw materials. The coal pitch is used as a binder. It is made by calcination, batching, kneading, pressing, roasting, graphitization and machining. It is a conductor that releases electrical energy in the form of an arc to heat and melt the charge in the arc furnace. According to the quality index and the size of the power allowed to pass, it can be divided into ordinary power, high power, and ultra-high power.
The General Classification of Graphite Electrodes
-
- (1) Ultra-high Power Graphite Electrode
- The UHP graphite electrodes with a current density greater than 25A/cm2 are allowed. Mainly used in ultra-high power steel-making electric arc furnace.
- (2) High Power Graphite Electrode
- It is allowed to use a graphite electrode with a current density of 18～25A/cm2. High-power electric arc furnace mainly used for steel making.
- (3) Ordinary Power Graphite Electrode
- RP graphite electrode is allowed to use the graphite electrode with a current density lower than 17A/m2. It is mainly used for ordinary power electric furnaces for steel making, silicon making, and yellow phosphorus making.
- (4) Oxidation-Resistant Coated Graphite Electrodes
- In order to prevent the oxidation loss of the graphite electrode, the graphite electrode is usually coated with an anti-oxidation protective layer. Therefore, a graphite electrode with an anti-oxidation coating is derived.
Advantages of Oxidation-Resistant Coated Graphite Electrodes
A layer of the anti-oxidation protective layer is coated on the surface of the graphite electrode, which is generally a graphite electrode antioxidant. Such a graphite electrode is called an anti-oxidation graphite electrode. The formation of anti-oxidation coating makes the original graphite electrode both conductive and resistant to high-temperature oxidation. Therefore, the advantages of oxidation-resistant coated graphite electrodes are highlighted during the steelmaking process.
-
- Reduce electrode consumption during steelmaking (19%~50%),
- Extend the service life of the electrode (22%~60%),
- Reduce the power consumption of the electrode.
Similarly, the use of antioxidant graphite electrodes can bring considerable economic and social benefits.
-
- The unit consumption of the graphite electrode is less, and the production cost is reduced to a certain extent. For example, a steel plant is calculated based on the consumption of 165 refining furnaces for the first-class LF refining furnace, which has no shutdown in the whole year, about 35 graphite electrodes per week. After adopting graphite electrode anti-oxidation technology, 373 (153 tons) electrodes can be saved every year. Based on the calculation of 16,900 yuan per ton of ultra-high-power electrodes per year, it can save 2.5857 million yuan.
- The graphite electrode consumes less power. The saved unit steel-making electricity consumption saves the production cost and saves energy!
- Because of less replacement of the graphite electrode, it reduces the labor and risk factor of the operator and improves production efficiency.
- Graphite electrode is a product with low consumption and low pollution. Today, energy conservation, emission reduction, and environmental protection are of great social significance.
