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.
