Danieli Corus has signed a contract with Severstal to modernize Blast Furnace No. 5 in Cherepovets, Russia, on a design and supply basis. Blast Furnace No. 5 'Severyanka' is the largest furnace at the Cherepovets Works and the flagship ironmaking operation for Severstal.

In 2005 Danieli Corus participated in the reconstruction project for Cherepovets' Blast Furnace No. 4 with the installation of a 'Hoogovens' design cooling and lining system. Following the outstanding performances achieved by that unit, Severstal decided to apply the same technology to the other blast furnaces, such as the 3290 m³ Blast Furnace No. 3 - which was successfully commissioned in December 2020 after a rebuild project executed by Severstal and Danieli Corus.

During the coming project, Blast Furnace No. 5 also will be equipped with the 'Hoogovens' design cooling and lining system in the bosh, belly and lower stack areas. This design is based on machined copper-plate coolers in combination with high-conductivity graphite, and is the only design with proven capability to achieve campaigns in excess of 20 years regardless of ironmaking process circumstances.

The revamped furnace will have a 5055 m³ working volume and 15.1 m hearth diameter.

Following the modernization, hot metal production by BF No.5 is scheduled to resume in 2023.
