TO AVOID ELECTRODE BREAKAGES

Malfunctioning of the electrode regulation causes a large percentage of electrode breakages.

Thus all mechanical and electrical components of the regulation system need to be in proper working order, raising and lowering of the electrodes should be adapted to the regularly features of the regulations merchant (response time)

To avoid breakages when the electrode is lowered onto the scrap, the lowering speed should be moderated, over current signals, which actuate rapid lifting of the electrodes reduce the risk of breakages in the event of scrap cave ins

Apart from the electrode regulation, the main cause of electrode breakages is the nature of the scrap and the manner of charging, care must therefore be taken in the preparation of scrap,

as well as in its transfer to buckets and its furnaces,

To avoid electrode breakages due to heavy scrap cave in is To prevent electrode breakages by non-conductive material; To avoid current over loading. Proper choice of claming force and contact area avoids overheating of the electrodes in the holders. Care should be taken to ensure that the electrode is not clamped closer to the end of a joint than the white rings. Perfect electrode jointing is very important.
