Electrode oxidation, sublimation, dissolution, spalling and breaking are all related to the cost of EAF steelmaking. Proper graphite electrode selection, use and maintenance can effectively reduce electrode consumption.
Matching relationship between electric furnace capacity, transformer power load and electrode size.
