U.S. Steel restarts Gary Works No. 14 furnace after $350M reline, upgrades
U.S. Steel has restarted the No. 14 blast furnace at its Gary Works in northwest Indiana after a $350 million reline, the company said on Thursday.
The Pittsburgh-based steelmaker said the furnace was not only relined but also went through “extensive” maintenance – including furnace gas, cooling water, hoisting, and stove systems.
“This investment positions Gary Works to continue serving customers, supporting American manufacturing, and creating value for years to come,” U.S. Steel President and CEO David Burritt said in a statement.
The No. 14 blast furnace, U.S. Steel’s largest, has annual capacity of more than two million tons of hot metal per year. Work to reline and upgrade the furnace began in May after the company’s board approved the major investment last December.
At its peak, the project employed approximately 1,000 people. And there were no days away for injury, the company added.
Recall that U.S. Steel’s parent company, Japan’s Nippon Steel, has committed to invest $11 billion in U.S. Steel by the end of 2028 after acquiring it last year for nearly $15 billion.
