graphite electrode High Power300mm

The types of graphite electrodes Electric arc steelmaking furnaces are generally classified into three types, namely, ordinary power electric furnaces, high-power electric furnaces and ultra-high-power electric furnaces. Corresponding to the power level of electric furnace steelmaking, graphite electrodes are also classified into three types accordingly, namely, ordinary power graphite electrodes (denoted as RP grade), high-power graphite electrodes (denoted as HP grade), and ultra-high power graphite electrodes (denoted as UHP grade). The nominal diameter of the electrode ranges from 75mm to 700mm. The physical and chemical properties of high-power and ultra-high-power graphite electrodes are superior to those of ordinary power graphite electrodes, such as lower resistivity, higher bulk density, higher mechanical strength, smaller linear expansion coefficient, and excellent oxidation resistance.
