Superior Quality Graphite Electrode UHP/HP/RP for Electric Arc Furnace
Superior Quality Graphite Electrode UHP/HP/RP for Electric Arc Furnace
RP graphite electrode is used in ordinary power electric arc furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting. Made of petroleum coke and coal pitch as raw materials. It is characterized by low ash content, good electrical conductivity, high temperature resistance, and does not melt or deform under high temperatures. RP graphite electrode as a conductive material in arc metallurgical furnaces for smelting various non-ferrous and rare metals. It can be used at current densities exceeding 17A/cm2.
HP graphite electrode is used in a high-power smelting furnace and a low-load to medium-load ladle furnace. Electric arc furnace steelmaking is to introduce current into the steelmaking furnace through electrodes, and the strong current passes through the gas at the lower end of the electrode to generate arc discharge. Then heat generated by the arc is used for eaf steelmaking. It is suitable for High-power electric furnaces with high power, high voltage, and short angle.
