Primetals Technologies Receives FAC from Severstal
- Twin ladle furnace treats 4.8 million metric tons of liquid steel per annum
- High degree of automation through Level 2 process models
- Production capacity of converter steel works increases to almost 10.3 million metric tons per annum
- Consolidation of liquid steel treatment significantly reduces operating costs
Russian steel producer PAO Severstal issued the Final Acceptance Certificate for a new twin ladle furnace supplied by Primetals Technologies to the converter steel works in Cherepovets. The ladle furnace is able to treat 375 metric ton charges of liquid steel with a treatment time not more than 45 minutes, and has an annual capacity of 4.8 million metric tons. This increases the production of converter steel from its previous maximum of 9.5 million to almost 10.3 million metric tons 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 million euros.
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 million metric tons 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 tons. 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 million euros to expand of its treatment capacity. Severstal and Primetals Technologies can look back on many years of close cooperation.
Primetals Technologies and Severstal welcome all steel industry professionals to visit their stands at Metal-Expo'2019, the 25th Jubilee International Exhibition, November 12-15, Hall 75, VDNHa, Moscow, Russia.
