Ironmaking facilities of LTV Steel's Cleveland works are spread across three sites. The C-5 and C-6 blast furnaces are sister furnaces located at one site. This plant was built as a Defense Plant Corp. project with the first blast furnace being C-5 in 1941. Blast furnace C-6 was added in 1951. When constructed, these furnaces were designed for a hot metal production of approximately 2000 NTHM/day each. Since that time, furnace productivity has been continually increased to what was considered a design limit of 3400 to 3600 NTHM/day each in 1988. The rebuild of these two furnaces was part of LTV's program to rebuild all of the company's core blast furnaces. C-5 and C-6 were to be the core furnaces for the Cleveland works. The goals for the rebuilds were: increase productivity to 4000 to 4200 NTHM/day with a 95.8% availability; extend furnace campaigns to 8 to 10 years with an intermediate 40 to 55-day outage at 4 to 5 years (6.5 to 7 million NTHM); complete project on planned outage schedule of 120 working days; and perform these jobs within budgeted costs. This article summarizes the strategies undertaken to achieve the primary project goals and focuses on problems encountered and lessons learned in the management and execution of the rebuilds.
