Failure modes to watch for
Every guide in the Danieli Danieli Q-One / Digimelter library lists the candidate root causes its procedure rules out. These are the distinct failure modes we've documented so far, a useful starting point if you don't yet know which specific alarm or symptom you're chasing.
Electrode mechanical stress from a scrap collapse event during the melt
Electrode nipple joint failure from over-tightening or under-tightening during column assembly
Deep boring of the electrode into a compact scrap pile causing bending
Electrode oxidation from excessive oxygen lance use near the electrode
Refractory lining worn thin from erosion by liquid steel and slag over the campaign
Arc hot spot in the dead zones of the furnace from incorrect electrode centering
Slag line erosion from fluctuating bath chemistry causing acidic or basic dissolution of the lining
Thermal shock cracks in the refractory from rapid temperature changes during charging
Tools you'll need most
These tools are referenced most often across the Danieli Danieli Q-One / Digimelter troubleshooting guides. If you service this equipment regularly, keep them on the cart.

How to respond to electrode breakage on a Danieli Q-One / Digimelter EAF
An electrode break stops melting on one phase. Stop the heat, raise the electrodes to the retracted position, and recover the broken stub from the scrap charge before jointing and continuing.
How to detect and manage furnace shell hot spots on a Danieli Q-One / Digimelter EAF
A hot spot on the EAF shell means the refractory lining is thin or damaged at that point. Stop the heat if the shell temperature approaches the critical limit and apply gunning refractory during the next planned stop.
How to detect and respond to water-cooled panel leaks on a Danieli Q-One / Digimelter EAF
Water entering a molten steel bath causes a violent steam explosion. If a panel leak is suspected, stop the heat immediately. Never continue melting with a confirmed water leak into the furnace.
