This is haut-fourneau 6 or HF6, a blast-furnace in the Liege region of Belgium. It was built in 1958 by SA Société Métallurgique d’Espérance-Longdoz, an ancient Belgian coal mining and steelmaking company dating back to 1836. The main steel production of this company were concentrated along the Meuse river: four blast furnaces (HF1-4), a steel plant, a coke plant and rolling mills.

At its start in 1959, the HF6 was amongst the largest and most technically advanced blast furnace in Europe. It had a capacity of 1800-2000 tons pig iron a day.
In 1970 Espérance-Longdoz and its facilities, included HF6, were taken over by the other Liège-based steel enterprise Cockerill-Ougrée-Providence. The resulting group was the fifth largest steelmaker in the European Economic Community.

The Cockerill group merged in 1981 with the Charleroi-based Hainaut-Sambre, giving birth to Cockerill-Sambre. In Liège only blast furnaces HF6 and HFB were left in activity.
During the ownership of Cockerill-Sambre, HF6 was largely renovated and refurbished. Further improvements occurred after the company’s transformation into Arcelor in 1999.
Nevertheless, in the first 2000s Arcelor announced its intention to progressively cease any steelmaking activity in the Liège area due to a persistent market crisis. HF6 was then turned off in 2005 but, thanks to a vast social mobilization and unions bargaining, it was not dismantled and thus kept for a possible future restart. One year later Arcelor merged with Mittal Steel, forming the largest steelmaking company worldwide Arcelor-Mittal.

The new owner restarted HF-6 in 2008. However, due to the global economic crisis and the fall of the price of steel the activity lasted for just nine months. In 2016 the dismantling and demolition process begun.
