EDUCING ELECTRODE CONSUMPTION

The most important factors influencing electrode consumption are as follows:

A. Electrical influences B. Mechanical influences C. Influences on oxidation D. Influences due to electrode handling

Electrode consumption governing influences

Tip consumption

---Current level ---Power on time ---Effect of slag ---Dipping of electrodes

Side consumption

---Oxidation of the graphite on the electrode surface ---Temperature ---Oxygen supply ---Electrode dimensions

Stub end losses (butt losses)

---Fluctuating thermal stresses ---Electrical load ---Current level ---Electrode joining ---Electrode regulation ---Electrode dipping
