Cleveland-Cliffs to Repair of Indiana Harbor East BF7 in September

US steel giant Cleveland-Cliffs plans to idle No 7 Blast Furnace at Indiana Harbor East in East Chicago for a planned maintenance outage

US steel giant Cleveland-Cliffs plans to idle No 7 Blast Furnace at Indiana Harbor East in East Chicago for a planned maintenance outage between September 1 and October 15. The outage includes repair to two BOF converters in the steel shop and a partial reline in several upgrades to the blast furnace. The blast furnace will be modernized to burn materials other than just the feedstock of iron ore, which should reduce its carbon footprint. Some of these upgrades are related to our ongoing work toward decarbonization, such as further enhancements to ability to use massive amounts of both hot-briquetted iron stock and natural gas as supplemental reduction at Indiana Harbor No 7 blast furnace.

Indiana Harbor Blast Furnace No 7 is the largest blast furnace in North America. It was built 41 years ago and can make up to 11,500 tons of hot metal a day. It was last relined in 2014, when then-owner ArcelorMittal invested USD 70 million in it.

The outage will take a financial toll on Cleveland-Cliffs by reducing production volume in the third quarter. But Cleveland-Cliffs has been stockpiling slab inventory to minimize the impact, so it can continue to supply customers during the disruption to production.
