U.S. Steel’s No. 4 blast furnace (BF4) at its Gary Works in northwest Indiana is undergoing a 45-day maintenance outage that started on April 4.
A spokesperson for the Pittsburgh-based steelmaker confirmed the news on Monday with SMU, noting that the maintenance would include shotcrete (sprayed concrete), among other projects.
U.S. Steel has four blast furnaces at Gary Works, according to SMU’s blast furnace status table, with BF4 having a daily capacity of 3,800 short tons (st). The other three are listed as running.
Gary Works is U. S. Steel’s largest manufacturing plant, with an annual raw steelmaking capability of 7.5 million st, according to its website.
Correction: An earlier version of this article listed the outage as the No. 8 blast furnace. This was the blast furnace provided at the time by U.S. Steel, and the company has since corrected it to BF4.
