The cost of unplanned downtime in metals and smelting operations
Unplanned downtime in metals and smelting operations is among the most expensive losses in the plant because a single failure, such as furnace and casting interruptions with very high restart cost, can stop the flow, not just one asset. The true cost pairs lost contribution margin with emergency labour and expedited parts, and is usually several multiples of the repair itself.
What drives downtime cost in metals and smelting operations
- Furnace and casting interruptions with very high restart cost.
- Cooling-water and hydraulic failures that force a stop.
- Cranes and materials handling that bottleneck the whole flow.
- Refractory and component wear deferred until it fails.
