The 1994 intermediate reline of H-3 furnace
Abstract
LTV Steel`s Indiana Harbor Works H-3 Blast Furnace was rebuilt in 1988 to provide reliable operations at high production rates without damage to the shell for an overall campaign. This Rebuild included: (1) complete bosh and partial stack shell replacement; (2) a spray cooled carbon bosh; (3) a row of staves at the mantle and six rows of stack staves, all stack staves had noses (ledges at the top of the stave) with the exception of row 5; (4) silicon carbide filled semi graphite brick for the bosh, silicon carbide brick from the mantle area and to the top of stave row No. 1, super duty brick in front of the remaining staves and phosphate bonded high alumina brick in the upper stack; (5) movable throat armor; (6) upgraded instrumentation to follow furnace operation and lining wear occurring in the furnace. No work was done to the hearth walls and bottom, since these had been replaced in 1982 with a first generation graphite cooled design and has experienced 7.7 million NTHM. The furnace was blown in November 18, 1988 and operated through September 3, 1994, at which time it was blown down for its first intermediate repair after 7.85 millionmore »
