NLMK Indiana earned AIST’s Gold Reliability Achievement Award for modernising its 118‑metric‑ton electric arc furnace. The six‑week project, co‑executed with Primetals Technologies, delivered 20+ heats daily after just four days. A single‑point roof lift and integrated gantry slashed safety incidents by 70% and reduced delta‑replacement time by 52%. Unscheduled stoppages fell 79%, adding 44,000 metric tons of annual output worth nearly $30 million.
