Arc radiation and splash eroding the refractory around the electrode ports over service life
Scrap or slag splash impacting the roof during charging or heating
Operating with the electrodes too close to the bath surface increasing roof exposure
Cooling water flow below specification in water-cooled roof panels adjacent to the hot zone
Electrode crack or partial break reducing the current cross-section
Contact shoe worn, leaving poor electrical contact between the arm and the electrode
Scum and slag floating on the bath surface creating arc instability
Power bus or flexible cable connection loose or corroded

How to diagnose electrode arc instability on a Danieli LF ladle furnace
Arc instability is most often caused by a worn or broken electrode, or contact arm current path deterioration. Inspect the electrode condition and the contact shoe contact before adjusting any controller parameter.
How to diagnose and clear a ladle bottom plug clog on a Danieli LF
No argon stirring with the valve open means the bottom plug is blocked by solidified steel. Test the plug with a high-pressure purge before labeling it failed; blocked plugs often clear with a brief pressure pulse.
How to inspect and manage roof refractory wear on a Danieli LF ladle furnace
Roof refractory wear around the electrode ports reduces the protective barrier and risks a burn-through. Inspect the roof at every planned stop and track minimum thickness against the replacement threshold.
