This increases the production of converter steel from its previous maximum of 9.5 mio. to almost 10.3 mio. metric t per annum. The additional ladle furnace also enables all the steel treatment to be brought together into a single section of the plant. This reduces annual operating costs by approximately € 10 mio.
The Cherepovets Metallurgical Plant in the Vologda region is part of the "Severstal Russian Steel" Division of PAO Severstal and is one of the world’s largest integrated iron and steel works. It produced around 11.65 mio. metric t of liquid steel in 2017. The steel is used to make a large number of end products, including hot- and cold-rolled flat steel, galvanized and coated products, and long products. The Cherepovets converter steel works has three converters, each with a capacity of 350 metric t. Until now, only one ladle furnace has been available for treating liquid steel supplied by Primetals in the past.
Primetals Technologies was responsible for engineering the twin ladle furnace, the alloying system, the dedusting system, and supplied key components. The scope of supply also included the associated electrical and automation equipment. The installed Level 2 system has been seamlessly integrated in the plant’s system and allows a high degree of automation due to the use of pre-calculated process models. In addition, Primetals Technologies supervised the installation and commissioning, and provided the staff training. Severstal was responsible for the technical documentation development and the construction activities. The company invested approximately € 43 mio. to expand of its treatment capacity. Severstal and Primetals Technologies can look back on many years of close cooperation.
