Dunaferr shut down its other blast furnace weeks earlier.

The company said lower steel prices paired with the unprecedented rise in energy prices, supply chain issues, and the war in Ukraine have put the company in a situation with which it is "unable to cope alone". Government support could give the company "a chance to survive" and continue to ensure work for its 4,500 employees, Dunaferr added.

Dunaferr said the "only solution" to its woes is the restart of coke deliveries by DBK "within a week, at the latest".
