Campaign Life Extension

Postponement of a blast furnace reline is a major decision for every integrated steelmaker. Large capital expenditure and loss of production must be balanced against the risks of sudden failures if the furnace life is extended. Campaign extension technologies are available for repairing the most critical areas in short stops, and, if emergency repair plans are in place, then it becomes possible to increase campaign life, or even adopt a “zero reline” philosophy within manageable risks.
