Influence factors of consumption
The electrode consumption, mainly on oxidation, breakage, end sublimation, slag action and electrode melt, accounts about 8%-10% of the production cost of electric steel. The characteristics of design and condition of the EAF, as well as the electrode quality have a close relation to general electrode consumption.
The major factors for electrode consumption are:
● Charge amount of method
● Charge time and power off time
● Tap cycle
● Exhaust emission and de-dusting system
● Electrode adjust
● High current, big slag
● Improper oxygen blowing
● Electrode operation and joining
● Electrode ontology quality and machining accuracy
● Strength of nipple
Therefore, suitable furnace data will be helpful for electrode selections.
