Product Detail

Product Tags

700mm UHP graphite electrode is made of high quality needlelike coke, which is formed, roasted, impregnated, graphitized and machineprocessed as a high quality conductive material for electric arc furnace.  UHP 700mm graphite electrode, The allowable current capacity is 73000 ~ 96000A, the allowable current density is 18-24A/㎡  .  It is designed for superpower electric arc furnace steelmaking.

Note: It is recommended that the current capacity be -10% for electric furnace and +10% for ladle furnace.
