Since the blast furnace process offers little opportunity for refractory repair during operation, the length of the blast furnace campaign is determined mainly by the life of the refractories. Today campaigns of 10 to 15 years are common, although numerous short stoppages must be planned for maintenance. ... HarbisonWalker International offers ...
