UHP650mm graphite electrode
UHP650mm graphite electrode
The UHP650mm graphite electrode is a special specification for steelmaking. In 2020, FANGDA,KFCC,and some other manufacturer started the production of UHP650mm

From 2021, we HAILICARBON FACTORY, also put into production for EGSP D600mm graphite electrode.

The brif specification as bellow.
