What are the main factors affecting graphite electrode consumption in electric arc furnace steelmaking?

Mainly include: 

(1) Filling amount and feeding method. 

(2) Feeding time and power-off time. 

(3) Smelting cycle. 

(4) Exhaust gas emission and dust removal system. 

(5) Electrode adjustment quality. 

(6) Load regulation quality. 

(7) Oxygen blowing operation. 

(8) The quality of electrode connection. 

(9) The quality of the electrode connector body. 

(10) Electrode joint hole and joint machining accuracy.

What matters should be paid attention to in the storage of graphite electrodes in steel mills?

The electrodes and connectors should be stored on a clean concrete floor to prevent the electrodes from being damaged or sticking to soil; do not remove the packaging for the electrodes that are not used temporarily to prevent dust and debris from falling on the connector threads or the electrode end face and the inner thread of the electrode hole superior. Electrodes should be neatly stored in the warehouse, and both ends of the electrode stack should be padded to prevent slipping. The stack height of the electrodes should generally not exceed two meters. The stored electrodes should be protected from rain and moisture to avoid cracks and accelerated oxidation of the electrodes during steelmaking. Do not store the electrode connector near high temperature to prevent the connector plug from melting and overflowing.
