What is Graphite Electrode
The graphite electrode raw materials are mainly needle coke and petroleum coke.Low resistivity, good electrical and thermal conductivity, good oxidation resistance, thermal shock resistance for electric arc furnace.
The electric arc furnace graphite electrode is a heat conductive material that releases electric energy in the form of an electric arc furnace to heat and melt the charge,the main raw materials are needle coke and petroleum coke,medium asphalt as a binder,after calcination, batching, kneading, pressing, co-firing, graphitization and machining, the product has low electrical resistivity, good electrical and thermal conductivity, good oxidation resistance, thermal shock resistance and mechanical vibration resistance, and mechanical High strength and high mechanical strength.
UHP Graphite Electrode in Arc Furnaces
The ultra-high power graphite electrode in Arc furnace is made of needle coke and is mainly used for ultra high power electric arc furnace steelmaking. EAF steelmaking is based on scrap steel, which has less investment than blast furnace converter technology and is beneficial to the recycling of scrap steel. With the development of the global steel industry, electric arc furnaces have gradually developed to large-scale, ultra-high power and automatic control of electronic computers. The use of ultra-high-power electric arc furnaces has been increasing, which has promoted the application of ultra-high-power graphite electrodes.
Graphite Electrode Manufacturing in China
Compared with the developed countries and regions such as the United States, Europe, and Japan, the development of China's ultra-high-power graphite electrode industry started late, mainly relying on imports at the earliest, and the production of ultra-high-power graphite electrodes is far from being able to supply demand. Driven by the development of the steel industry and the advancement of technology, China has gradually broken the monopoly of foreign technology. The production capacity of ultra-high-power graphite electrodes has been rising and the quality of products has been rapidly improved. At present, the ultra-high power graphite electrodes produced in China have achieved good results on large-scale electric arc furnaces, and the performance indexes of the products can reach the international leading level. China's ultra-high-power graphite electrode products are not only supplied to the domestic market, but also exported to foreign countries in large quantities, with less demand for imported products.
Although China's ultra-high power graphite electrode industry has achieved rapid development, the raw material needle coke is still dependent on imports. At present, the world can produce needle coke on a large scale in the United States, Japan and other countries. The United States only produces oil-based needle coke, Japan. Both coal and oil needle coke can be produced. In recent years, China's needle coke research and development has made breakthrough progress and achieved industrial production, but in terms of quality, compared with foreign high-quality needle coke, there is still a certain gap.
