What are the factors that affect the consumption of electrode in EAF steelmaking ?

Factors affecting the consumption of electrode mainly include: 

1) charge amount and the feeding way. 

2) feeding time and outage time. 

3) Tap-to-tap time.

4) emissions and dust removal system.

5) electrode adjustment, 

6) high current, large amount of slag. 

7) improper oxygen injection. 

8) electrode connection and joint.
