The ultra-high power graphite electrode is made of high-quality needle coke, which is produced through more than a dozen processes such as calcination, extrusion, impregnation, graphitization and machining. long. It allows the current density to be greater than 25A/cm2, and is mainly used for smelting fine steel and special steel.

In the early days, domestic ultra-high-power graphite electrodes relied heavily on imports. Due to the technology monopoly of developed countries in Europe, America and Japan, domestic production was far from meeting demand. With the development of the steel industry, many graphite electrode

manufacturers have invested a lot of money and technology in R&D and production of ultra-high power graphite electrodes. Dan charcoal graphite electrodes have achieved UHP700mm ultra-high power graphite electrodes to provide foreign steel mills with qualified trials and mass production. UHP800mm has been fully developed. Ultra-high power graphite electrodes.
