Danieli Corus has signed a contract with Severstal to modernize Blast Furnace No 5 in Cherepovets in 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.
During the coming project, Blast Furnace No 5 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 cubic meters working volume and 15.1 meter hearth diameter. Following the modernization, hot metal production by BF No 5 is scheduled to resume in 2023.
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 cubic meters Blast Furnace No 3,- which was successfully commissioned in December 2020 after a rebuild project executed by Severstal and Danieli Corus.
