Uhp graphite electrodes are used in ultra-high-power electric arc furnace steelmaking, and the melting power per ton of furnace is more than 500kv.a/t.
Uhp graphite electrode useg
UHP graphite electrodes mainly use high-quality petroleum coke and needle coke as raw materials, and are formed by calcination, extrusion, impregnation, graphitization and mechanical processing. It is a conductive rod used in ultra-high power electric arc furnace steelmaking.
When UHP graphite electrodes are used, the trend of steelmaking technology development in the future, the United States and Japan ultra-high power electric arc furnaces have developed rapidly, and almost all large-capacity electric arc furnaces use UHP graphite electrodes.
UHP graphite electrode technical data steel
In the future, the capacity of electric arc furnaces will become larger and larger, the resistivity of UHP graphite electrodes is low (5 ~ 6μΩm), and the allowable current density is more than 30A/cm2. In addition, the coefficient of thermal expansion is low and the mechanical strength is high, which will not cause cracks and breaks.
Electric arc furnace electrodes are mainly used in the Ac steelmaking arc furnace and Dc steelmaking arc furnace.
Electric arc furnace grade matched with electrode graphite diameter:
Uhp graphite electrode 800mm supplier
At present, the UHP graphite electrode with a diameter of 800mm has a long production cycle and high process requirements, and the yield rate of each batch produced is low, which makes many graphite electrode manufacturers unwilling to produce. Dan Carbon graphite electrodes have been supplied to Japanese steel plants in 2019 and passed the trial, and customer feedback is good. If you need 800mm UHP graphite electrodes, you need to book with our Dan carbon graphite electrodes in advance because the production cycle is longer.
