What are the measures to reduce the consumption of electrode oxidation in EAF furnace steelmaking process?

Reducing measures mainly include: 

1) to reduce the oxidation consumption of electrode perimeter, strengthen the sealing of the furnace, and reduce air intrude into the furnace; to minimize the exposure time of overheated electrodes outside the furnace, and standardize oxygen blowing operation. 

2) if conditions permit, adopting spray cooling technology to effectively reduce the electrode side oxygen consumption in EAF furnace. 

3) steel mills could spray antioxidant substances on electrode surface, or the electrode manufacture can take antioxidants impregnation treatment technology before delivery to improve the oxidation resistance of electrode ontology.
