The background for the decision to partially reline No. 7 blast furnace that would achieve the same results as a complete reline is discussed. This approach was designed to reduce actual downtime on the furnace at a critical production period. Areas of work included the hearth, stack, stoves, gas cleaning and furnace top. Highlights of the project execution were: schedules; blowdown; salamander tap; quench; dig out/descale; scaffolding used; and brick installation. The furnace was blown-in 29 days after the blowdown and producing in excess of 9,000 tons/day after 12 days of operation. Inland has adopted a new definition for establishing campaign life based on refractory wear that includes a hearth monitoring system.
