According to the results of the first quarter of 2021, 2500 hot rolling mill located in the sheet-rolling shop No 4 of the Magnitogorsk Iron and Steel Works produced 1,077 thousand tonnes of hot rolled products. This is the maximum indicator of quarterly production for this unit in the entire post-Soviet history. A significant increase in the performance of the unit, which celebrated its 60th anniversary in December last year, was largely made possible by the comprehensive reconstruction completed in 2020. The completely modernized hot rolling mill 2500 at PJSC MMK is today one of the most modern and highly productive in the world. The last time the 2500 mill crossed the mark of 1 million tonnes of hot rolled steel was in three months of operation in 2008, and the result obtained in the first quarter has not been achieved since 1991. The large-scale reconstruction of Mill 2500 at Rolling Shop No 4 made it possible to expand the size and grade of the mill. The quality of products has significantly improved, and the production capacity of the unit has increased to 5.2 million tonnes of rolled metal per year.
