Danieli Corus to modernize Severstal Cherepovets Blast Furnace No. 5
The third installation of an advanced BF cooling and lining system for the leading Russian steelmaker
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.
