U.S. Steel has completed a 25-day maintenance outage on the No. 1 blast furnace at its Mon Valley Works in western Pennsylvania, a company spokeswoman said.

The outage was part of the steelmaker’s normal maintenance program. The downtime was used to apply shotcrete–a sprayed concrete–and other standard upkeep, sources have said.

US SteelThe Pittsburgh-based steelmaker said on its first-quarter earnings call on Friday, April 30, that it had begun the previously announced outage.

Steel Market Update has updated its blast furnace status table, found by clicking here, to reflect the development.

Mon Valley Works has two blast furnaces: No. 1 and No. 3. The No. 1 furnace has daily ironmaking capacity of approximately 3,200 tons. The No. 3 furnace has daily capacity of approximately 2,900 tons.

The furnaces are located at U.S. Steel’s Edgar Thomson Plant in Braddock, Pa. Edgar Thomson produces liquid metal, which is cast into steel slabs. Those slabs are then railed to the company’s Irvin Plant in West Mifflin, Pa., where they are rolled into steel sheet.
