Model NO.：700UHP Grade: UHP (Ultra High Power) Application: melt scraps, DRI, etc. by arc energy Applicable Nipple NO.: 374T4N/374T4L
UHP graphite electrode are mostly made of 100% high-specification needle coke. Compared with HP and RP grades, UHP electrode requires highest technical expertise in each of the main process steps in making them, particularly baking, extrusion and graphitizing. The electrodes come with a wide range of sizes, but diameter of 600mm and 700mm high performance. UHP graphite electrode is often used for ultra high power electric arc furnaces (EAF) with current density greater than 25 A/cm2.
