THE CAUSE OF ELECTRODE BREAKAGE

Electrode is stressed decreasingly downward; the electrodes and nipples under the clamping device take maximum force.

When electrodes receive external force, in case of the concentration of the external force is greater than the electrode strength, the electrode will break.

The causes of external force are: bulk charge collapse during melting , non-conductive objects below the electrode in the scraps; impact of massive steel bulk flow and etc.

uncoordinated response speed of clamping device lifting/descending; eccentric electrode hole of lid; gap because of bad connection of electrodes, and requested nipple strength is not reached.

Electrodes and nipples with poor machining accuracy.
