NLMK boosts sustainability of blast furnace operations

05 February 2021 

NLMK Lipetsk has completed an upgrade of Blast Furnace No. 4 with a capacity of 2.1 m t of pig iron per year.

The project includes an environmental upgrade of the furnace infrastructure. All the dust generated during hot metal production will be captured by a highly efficient dedusting system. The system ensures a purification efficiency of 99.9%, which is in line with the best available technologies. The new equipment will also enable more efficient blast furnace gas treatment for it to be utilized as a secondary energy source. Filtered dust will be utilized in the production of iron-containing briquettes, or fed back into the blast furnace process.
